Title: The Yam Checklist: Starting a Backyard Dioscorea Germplasm Collection
Post by: Caesar on July 07, 2018, 12:37:37 AM
Well, I think I finally cracked. I went too deep, and now I mostly have yams on the brain. But that's okay... I'll never go hungry with a good yam collection.  ;)

Having read the 6 documents of "Tropical Yams and their Potential", as well as other sources, I've come up with a list of yams that I'm looking to collect, multiply and disseminate to other growers (these are marked with a checkmark: ✓). I've also listed a couple of other yams that are deemed edible by the literature, but that don't strongly catch my attention (also marked with a checkmark anyway: ✓), have been outright rejected (these are marked with an X), or have poorly-known qualities regarding their edibility (asterism: ⁂ ).

The Big 5 (or 8, depending on how you segregate the species): ✓
1 - D. rotundata (White Guinea Yam) + D. cayennensis (Yellow Guinea Yam)
2 - D. alata (Greater / Winged Yam) + D. purpurea (Ube / Purple Yam)
3 - D. bulbifera (Asian Air Potato) + D. latifolia (African Air Potato)
4 - D. esculenta (Lesser / Potato Yam)
5 - D. trifida (Cushcush / Mapuey Yam)

The Lesser 5:
1 - D. pentaphylla (Five-leaf Yam) - ✓
2 - D. transversa (Australian / Pencil Yam) - ✓
3 - D. nummularia (Pacific Yam) - ✓
4 - D. dumetorum (Trifoliate Yam) - ¿✓?
5 - D. hispida (Intoxicating Yam; also known as D. reticulata) - X

The Temperate 3: ✓
1 - D. polystachya (Nagaimo / Chinese Yam; also known as D. oppositifolia & D. batatas)
2 - D. japonica (Japanese Yam)
3 - D. hamiltonii (¿Nameless? I'd just call it Hamilton's Yam)

The Leftovers? (not a great name, but  don't know what else to call 'em; it doesn't mean they're of bad quality):
1 - ¿D. pseudo-tomentosa? (¿Nameless?) - ✓
2 - D. remotiflora ("Camote de Cerro" / Mexican Mountain Yam) - ✓
3 - D. dodecaneura (Ornamental Yam) - ✓
4 - D. orangeana (¿Madagascar Yam?) - ⁂
5 - D. brachybotrya ("Papa Cimarrona" / "Jaboncillo") - X
6 - D. humifusa ("Huanqui") - X
7 - D. deltoidea (¿Nameless?) - X
8 - D. rupicola (¿Elephant's Foot?) - ⁂
9 - D. altissima (Dunguey) - ⁂
10 - Rajania cordata ("Ñame Gulembo") - ¿X?

I'm currently growing D. rotundata, alata, purpurea, bulbifera, trifida, and polystachya. I have some possible sources to check out for D. esculenta, japonica, latifolia and additional strains of bulbifera. D. cayennensis eludes me, but though I'm sure it's here in Puerto Rico, it's not common nor easy to find (if anyone has some, send 'em my way).

I recently received a mystery yam in the mail from eBay, but it arrived so thoroughly dried out that I don't expect it to survive (though the vendor assures me that it should or they'd reimburse me, which I declined); nevertheless, I planted it anyway and hope against hope that I'll get something out of it. It was sold as a D. pentaphylla, but the vine photos reminded me of alata, and the bulbil photos resembled bulbifera. The vendor confirmed it was not pentaphylla, but I bought it anyway 'cause it was cheap and I felt like trying it out. At any rate, the vendor confirmed that it was fully edible, bulbils-and-all, so I considered it valuable anyway. If it survives, I hope to be able to deduce the species from the anatomy.

I have some D. hamiltonii seeds coming in the mail, as well as some true pentaphylla bulbils. When asked about the pentaphylla bulbils (as opposed to the tuber), the vendor said they don't eat them, but they never explicitly confirmed that they were toxic. I'd really like to know if they're edible, but since there are toxic pentaphylla strains out there, I'm reluctant to try them; if I could find a lab able and willing to analyze a cooked sample, I could lay that doubt to rest. The tuber was confirmed to be edible steamed.

There's another mystery yam coming in the mail, sold as D. pseudo-tomentosa. I couldn't find anything in the literature about this species being edible (or toxic), only that it's endangered. The photos of the yam may have vaguely resembled D. esculenta, but I may be reaching with that conclusion. Truth be told, I'd love for it to be genuine D. pseudo-tomentosa, to add another good species to the germplasm. Link here (https://m.ebay.com/itm/UNCLE-CHAN-2-bulbs-Dioscorea-pseudo-tomentosa-THAI-POTATO-GUMMY-EDIBLE-YUMMY/152763087745?hash=item239163bb81:g:TOQAAOSwEOpZ9K4q).

D. transversa is very high on my wish list (specifically the large-tubered bulbil-bearing strain), but no luck finding it yet. No idea where to find D. nummularia (which is said to closely resemble rotundata), but I also consider it important as a supposedly good-quality species. Interestingly, one document claimed that some nummularia cultivars were introduced to Puerto Rico; also, there seems to be some confusion in the literature whether to consider the cultivar "Wael" as a type of transversa or of nummularia.

I don't object to D. dumetorum if I can obtain it, but I'm not really looking for this one. The best strains still seem like poor quality yams and they have to be eaten quickly after harvesting or they turn hard (even after cooking) and difficult to peel (as if their strange shape didn't already make that a challenge). The worst strains are downright toxic, which leads me to its close relative... I don't even know how D. hispida made it into the original documents. I don't even care that they have in-fact been eaten before (and they're probably still eaten to this day), even the best strains are dangerously toxic and require jumping through hoops to detoxify and turn them edible, and we all know how I feel about that... Famine food. So I just mentioned it for completion's sake, but I don't consider that species edible, nor am I interested in it in the slightest.

D. remotiflora is an edible wild mexican yam that barely even has a presence in the literature. If it weren't for a single isolated YouTube video (link here (https://youtu.be/PCHfYNfh06I)) showing its harvest, I wouldn't even know this species was edible. It seems to bear some resemblance to D. polystachya, which is also referred to as "Camote de Cerro" in Mexico. As it seems to be rare and difficult to find, with few traits to explicitly recommend it, I won't go out of my way looking for it. But if someone out there has some and is willing to share, I'd be very grateful nonetheless.

D. dodecaneura doesn't seem like an especially important species, but it is listed in several sources as being edible raw or cooked with an almond-like flavor; it's also a beautiful ornamental. I'm kinda interested in it. A few links: Link 1 (http://tropical.theferns.info/viewtropical.php?id=Dioscorea+dodecaneura), Link 2 (https://unusualediblesandtheirwildrelatives.blogspot.com/2018/02/ornamental-yam-dioscorea-dodecaneura.html?m=1), Link 3 (https://meueternoceu.blogspot.com/2016/01/060-cara-da-terra.html?m=1)

D. orangeana is Madagascar's only edible native Dioscorea, and is a recent discovery. I've yet to find an online source that knows anything about it, or if it's even conventionally edible (as opposed to a hispida-like famine food). Unless it's explicitly confirmed as conventionally edible, I'm not too interested in it (and even then, it's like remotiflora, where it's so rare I'm not sure it's worth going out of my way for it).

I saw brachybotrya, humifusa, deltoidea and rupicola on a YouTube video (link here (https://youtu.be/bPeKBm2Qy68)) where a guy was trying to germinate them from seed (along with other rare supposedly edible species... like reticulata/hispida). When checked online, the Chilean brachybotrya & humifusa turned out to be toxic and bitter (¿saponins?), and probably require special preparation, so I'm not interested in either as a crop. Deltoidea from Asia was also said to be bitter but edible in PFAF, though the article (link here (https://www.pfaf.org/user/Plant.aspx?LatinName=Dioscorea+deltoidea)) urged caution, and mentioned that it's boiled with wood ashes to remove bitterness. It doesn't seem like a good prospect either, so I'm not interested. Regarding rupicola, I could barely find anything about it online, but one seed seller claims it to be edible (link here (http://scamptonsucculents.mybisi.com/product/easy-to-grow-wild-yam-fresh-seeds)). I couldn't see the details because when I clicked the link it failed to open for me. Maybe the link will work for one of you and you can post the screenshot. At any rate, I'll be interested if it turns out to be conventionally edible, but as a desert plant I doubt it'd be particularly prolific as a crop, so I probably wouldn't go out of my way for it anyway.

Edit: Another species:
D. altissima was present in another seed sowing video. There's not much in the literature about it, but it's apparently wild harvested and occasionally home grown for its edible tubers in parts of its native range in South America; it's also present in Puerto Rico. A photo search revealed a very thorny stem and small aerial bulbils. I wouldn't grow it from anything other than seeds, for fear that it might carry the same virus as R. cordata, but since there's no details available on preparation & toxicity level (¿Conventionally edible? ¿Detoxification necessary?), I'm not too interested in trying it... Maybe a little. Info link here (http://tropical.theferns.info/viewtropical.php?id=Dioscorea+altissima).

And finally, Rajania cordata, our very own Ñame Gulembo. It's a close relative of Dioscorea. I don't recall having tasted this one (though I might be mistaken). I'll have to ask around for am account of its flavor, but my grandmother mentions that it is fibrous. It grows wild in the mountains of Puerto Rico and is wild-harvested here. So why have I rejected it? Because it is a carrier of a virus that is a very nasty disease of D. trifida (and also affects other species, to varying degrees). That's a big risk for a crop that's probably not very decent (though it requires no special preparation). Why the question marks? Well, I've yet to find out if the seeds carry the disease. If they don't, I wouldn't mind trying my hand at this species. But first I need assurance that I'm not endangering my other yams before I'd be willing to even consider it.

***

So this is a taste of what I wish to achieve. There's a lot of edible yam roots out there, and I wanna grow as many as I can, especially the better types, and help get them to other interested growers. It seems absurd to me that something as widespread, productive and gastronomically wholesome as the air potato was so hard for me to find in the first place. And it seems even weirder that other good yams (which don't have the same legal issues) seem even harder to find. So let's get a good germplasm collection up and running to get these species into the hands of other hobbyists. The more people join our exchange network, the better.

WOW!!! You are The Yam King!  ;D
Thank you very much for this great info!

Haha, the Yam King... I like the sound of that. But surely the original document authors have me beat in that regard. I remember that when I first got into agriculture, having decided to become a farmer, I'd facetiously tell my friends that my work would be growing yams in the hillsides. I never imagined that I'd actually be dreaming of doing just that. Oh well, yams are only part of it, I love all edible crops. I hope I'll be able to get a piece of land soon.

I took some photos of the backyard, particularly the yam trellises. Please disregard the mess, I need to clean up soon.  ;)

Here's the pvc trellis, still under construction (just a couple of posts so far). I'll add some t-jointed side bars on top, and link everything with clotheslines. I'll also link it to the bamboo trellis, with which it's perpendicular at the corners.
(https://s22.postimg.cc/y4q6thv9p/image.jpg) (https://postimg.cc/image/y4q6thv9p/)

Here's the bamboo trellis, with some very vigorous bulbifera vines reaching past it and into the big pigeon pea bush in the side yard... They'll be reaching the Açaí palms soon!
(https://s22.postimg.cc/64m39dk59/image.jpg) (https://postimg.cc/image/64m39dk59/)(https://s22.postimg.cc/ezmxjxj8d/image.jpg) (https://postimg.cc/image/ezmxjxj8d/)(https://s22.postimg.cc/ij8v9q6il/image.jpg) (https://postimg.cc/image/ij8v9q6il/)(https://s22.postimg.cc/x2g0b57d9/image.jpg) (https://postimg.cc/image/x2g0b57d9/)(https://s22.postimg.cc/iw09fxbxp/image.jpg) (https://postimg.cc/image/iw09fxbxp/)(https://s22.postimg.cc/pmgqpd6t9/image.jpg) (https://postimg.cc/image/pmgqpd6t9/)

The bulbifera tote (six plus the original rotundata and a trifida), the tomato tote (with a second rotundata strain, a trifida and the two alatas - one of them the purpurea strain) and the Lerén tote (three of these, with four potato mints and six trifidas):

(https://s22.postimg.cc/h5h8ei7a5/image.jpg) (https://postimg.cc/image/h5h8ei7a5/)(https://s22.postimg.cc/kcbry31zx/image.jpg) (https://postimg.cc/image/kcbry31zx/)(https://s22.postimg.cc/c6tpzyvrh/image.jpg) (https://postimg.cc/image/c6tpzyvrh/)(https://s22.postimg.cc/5t4mwpj5p/image.jpg) (https://postimg.cc/image/5t4mwpj5p/)

And a nice view of the rotundata growing up alongside the bulbifera:
(https://s22.postimg.cc/4e3283se5/image.jpg) (https://postimg.cc/image/4e3283se5/)

I'll be adding more totes over time, as well as a few buckets for those that I'd like to grow more isolated or compact (like the polystachya & hamiltonii). The green tote off to the side (currently housing some turmeric that I'll move to the ground) will house the Hodgsonia vines.

I forgot to post a pic of my dried up mystery bulbils, so here it is:
(https://s22.postimg.cc/3v6p6zw99/image.jpg) (https://postimg.cc/image/3v6p6zw99/)

And the links to the pentaphylla bulbils (I bought the first one):
Link 1 (https://m.ebay.com/itm/3-Bulb-Dioscorea-pentaphylla-Air-Potato-thai-/182843901979?txnId=1837985198008), and Link 2 (https://m.ebay.com/itm/3-Bulb-Dioscorea-pentaphylla-L-local-seasonal-fruits-of-Thailand-Thai-herbs-/253700392951).

Also, either I misread the information or it was outdated, because I found two to four extra Yams from Madagascar that are allegedly edible: D. acuminata and/or D. maciba, and D. alatipes and/or D. bako.

Hi! That's great! But this bulbs rehidrate and growth?
Title: Re: The Yam Checklist: Starting a Backyard Dioscorea Germplasm Collection
Post by: Caesar on July 10, 2018, 02:38:18 PM
I did rehydrate them prior to sowing, but my concern was the extent to which they were dried, the fact that some were apparently squished in the package, and the fact that all of them had already sprouted, and the sprouts were nothing but dried twigs at this point. They'll probably succumb to rotting, but I'm still praying for a miracle.

I got my D. hamiltonii seeds yesterday, I think there were like 30 in the package. I planted 10 in a jar covered with plastic wrap to preserve moisture, and soaked the rest, per the instructions. I'll be planting those soon in a plastic pot.

You are the yam King! Agree with above poster.

I too am into yams but haven't been able to source many varieties that are edible. Only have the D. alata purple type and D. opposita. Would love any you could share! I'm going to make a post shortly with a list of plants I have available. Maybe we could trade???

Definitely! I'll have material available as soon as the vines die back, maybe somewhere around November - March.

I managed to contact the local Ag. Station in Corozal, where they apparently specialize in Yams. I'm not sure how many varieties they have, but they explicitly confirmed that they have several varieties of D. esculenta, as well as several each of D. alata, D. rotundata and D. trifida. They'll have stock ready later in the year as well, which I'll acquire and plant for next year. I'm gonna give them some of my bulbiferas, so they can evaluate the variety as well. If I give them a bulbil, they won't be able to give it a fair shot until the year after, but if I give them an in-ground tuber, they should get a mature productive vine in their first year. Hmm... I think I can spare a tuber.

Speaking of my bulbifera, I reviewed parts of TYATP (Tropical Yams and their Potential) again, and I'm fairly confident that my bulbifera is varietas "Sativa". Of the asian bulbiferas, there are four varieties: two small-bulbilled wild types (distinguished from each other by leaf shape), Suavior (which is characterized by prominent lenticels on large mature bulbils), and Sativa (which is characterized by smooth-skinned large mature bulbils). Mine only had noticeable lenticels during early development, but they always matured smooth. Incidentally, TYATP explicitly stated that the bulbiferas from India and South East Asia were both tastier and way more productive than the African bulbiferas (the ones I prefer to call latifolia, to distinguish them). It kinda makes me wonder why the African types appear to be more common among those growing bulbiferas. Also, they had a table with data collected from a large collection of different bulbifera cultivars (now defunct, curtesy of the USDA, to which it belonged), and their Sativa accession (from India, like my own) far outproduced all other cultivars, even other Asian types. The only one that produced more bulbils was a New Caledonian type, which thoroughly underproduced the in-ground tuber (unlike Sativa, which was a good producer of tubers). I'll post screenshots of the relevant pages:

(https://s22.postimg.cc/m3yv4163h/image.png) (https://postimg.cc/image/m3yv4163h/)(https://s22.postimg.cc/6v8xq9k4t/image.png) (https://postimg.cc/image/6v8xq9k4t/)


Another fact I recently learned from these documents is that D. hamiltonii (which I'm now trying to germinate) is a close relative (and probable ancestor) of D. alata. I didn't expect that, given its tolerance for cooler conditions than alata. Then there's the fact that some types of D. rotundata can be cropped twice in one year, which is something I'd like to try myself. Relevant pages here:

I'm quoting and posting all these screenshots, and it hadn't occurred to me to post the original documents, so here they are, in full downloadable PDF glory: Tropical Yams And Their Potential, Parts 1 - 6:

Very awesome man! Just let me know when you have anything ready to trade/sell. I'm down for any and all edible yam varieties. You've done the work I've planned to do for some time. I'm a survival gardening minded guy and seek to have many varieties in the event of who knows what. Yams are perfect for such application being that they need very little attention over time with potential to be heavy producers. Got other root veggies that may interest you whenever.

Yams are productive and, as far as I'm concerned, the tastiest roots. I'm looking forward to the trade, it'll be the first time I make something available forum-wide. I hope I manage to get good material safely to everyone involved.


I have some varieties of yam in my garden. Is there any manual/book describing the varieties which could help me to classify my varieties ?

The book links I posted in my last post explain the anatomy of the varieties, but I'll sum up the information on the most prominent distinctions. When talking about leaves, I mean the leaves on the upper portion of mature vines. Leaves on the lowest portion, as well as on young vines, can sometimes develop in a different configuration (usually alternate on a vine that otherwise has paired leaves).

Vines that twist to the left (lower right to upper left: the "S" twist):
D. esculenta
D. bulbifera
D. trifida
D. pentaphylla
D. dumetorum

Vines that twist to the right (lower left to upper right: the "Z" twist):
D. rotundata & cayennensis
D. alata
D. nummularia
D. transversa
D. polystachya
D. japonica
D. hamiltonii

Paired Leaves:
D. rotundata & cayennensis
D. alata
D. nummularia
D. polystachya
D. japonica
D. hamiltonii

Alternate Leaves:
D. esculenta
D. bulbifera
D. trifida
D. transversa
D. pentaphylla
D. dumetorum

Pentaphylla leaves are divided into 5 leaflets, dumetorum into 3, the rest are singular. Trifida leaves are somewhat palmate, and other than the rounded leaflets of pentaphylla and dumetorum, the rest are heart-shaped (with varying ratios of length-breadth and varying degrees of rounded to angular corners).

Trifida, alata and hamiltonii stems have ridges/wings (which can be substituted by corresponding ridges of spines in some varieties of alata). Rotundata, cayennensis, esculenta, pentaphylla and dumetorum stems tend to be spined or prickly; the rest are smooth (though some species, like nummularia, can have prickles at the base). Bulbifera and nummularia have round stems, polystachya has a square stem. Dumetorum is highly pubescent/fuzzy.

Bulbifera has round bulbils (usually large, but tiny ones are also produced), polystachya and japonica bulbils can be round or oval, and are always small. Alata bulbils are ovoid to long & irregular, and are small to medium sized. Pentaphylla bulbils (allegedly not edible) are small to medium sized and horseshoe shaped, and dumetorum bulbils (probably toxic) are spiny. I'm not sure how transversa bulbils are, but only some varieties produce them. The rest don't usually produce bulbils. Bulbifera is a reliable producer of bulbils, whereas not all varieties of alata produce bulbils (and those that do aren't usually as productive as bulbifera).

Those are the main distinctions, but there's always variation among the species listed, never mind those that I didn't get to list, which should have further differences. Can you take closeup pictures of your vines? Leaves, lower and upper stems and how the stems curl? They might be easy to identify right here.

*

My Ube kept declining, so after examining the roots (which already had a new tuber forming, with the old tuber not fully deteriorated) I cut the vine to a stump (hoping for it to branch, or for a new one to form from the base) and replanted it in a small pot for observation. I accidentally knocked off the old tuber, and I'm really hoping I can get a second vine from it.

The first mystery yam bulbils have rotted away. Only two remain, and I think they'll rot soon enough. The second mystery yam (sold as D. pseudo-tomentosa) arrived in the mail, suspiciously packaged identically to the first mystery yam, despite being a separate Thai eBay seller. That said, while dry, they definitely seemed to be in much better condition, and even seemed to have some sprouts forming. I'm cautiously optimistic that I'll get them to grow without losing them. Here's some pics:

(https://s22.postimg.cc/adkiqw165/image.jpg) (https://postimg.cc/image/adkiqw165/)(https://s22.postimg.cc/owrnsczgt/image.jpg) (https://postimg.cc/image/owrnsczgt/)(https://s22.postimg.cc/qbt8h389p/image.jpg) (https://postimg.cc/image/qbt8h389p/)(https://s22.postimg.cc/8yiy27i3h/image.jpg) (https://postimg.cc/image/8yiy27i3h/)

The pentaphylla bulbils have yet to arrive, and I'm a little worried about the state they'll be in. I'm also waiting on an alata (which I bought thinking I'd get a dumetorum due to the photos used), a cayennensis, and some non-Dioscoreas: an Elephant-foot Yam (Amorphophallus paeoniifolius), some Ensete ventricosum seeds and Roy's Hogdsonia seeds. It's exiting to expect something in the mail every day, and a little nerve-wracking (you'll never know when it'll arrive and in what state it'll be in).

There's a guy named David Goodman aka "the survival gardener" you can find online whom has many varieties of yam. Perhaps if you can talk with him he may have some unusual types. Definitely worth contacting him. Had some with palmate leaves and such he randomly found around the place he lives in street markets etc. All varieties grown by the natives of the area. Somewhere in the Caribbean or Central America.

I commented on a video of his a few days ago, but I think I was a little late to the party. Perhaps I would've had better luck commenting on one of his blog posts, but I'm waiting for him to post something relevant; I don't wanna hijack a thread from another topic to talk about yams. Unless there's a way to message him directly?

I've been scouring the net looking for other growers of edible D. bulbifera (and other rare types), and messaging every one I can. So far, I haven't had much in the way of answers, but I'm hoping to find something sooner or later. The more bulbifera clones I have, the better the comparison I can make regarding productivity and quality, not to mention the breeding possibilities.

I found a source for D. hispida. I'm not getting it, but since I found it I might as well post it for any interested parties. They explicitly mention that it requires processing for toxicity, so there ya go: link here (https://www.etsy.com/listing/594882960/1-bub-dioscorea-hispida-rare-collcted?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=dioscorea&ref=sr_gallery-1-47).

Should be able to get ahold of David's e-mail somewhere online. Probably his personal blog. I have emailed him directly in the distant past.

There's a guy in or near Orlando FL that has the edible bulbifera supposedly. Grower Jim is the name to look for. Sells on eBay but won't ship bulbifera to other within FL people.

Pineislander is talking to Jim, so if there's material to be shared I expect he'll get it this year and be sending it out from next year's harvest. Though I wouldn't mind talking to Jim myself to see if he knows of additional sources for other varieties.

As for eBay, all the currently available bulbifera growers I've tried are selling theirs as medicinal, not edible, so there's nothing there.

I'm still waiting on a reply from YouTube's Plant Assasin, as well as a guy from India who blogged about seeing (and I think growing) three Asian cultivars (seemingly Suavior, judging from the prominent lenticels). I don't know if I'm expecting too much, considering the date of that post (2015), but I really hope he replies. Blog here (http://nandanvana.blogspot.com/2015/05/air-potato-dioscorea-bulbifera.html?m=1). I'm considering contacting the Agricultural University mentioned in the blog post, but I'm not exactly sure how I'd go about it... That said, their variety is an improved Suavior developed by them, so I'd consider it important. I think I'll contact them sooner or later, though I'm not sure they'd be willing to ship to a random overseas grower.

I found out today that Rare Palm Seeds is selling D. bulbifera as a new item. After some trial and error figuring out the proper extensions, I called their office in Germany and confirmed that it is an edible Asian type. I combined it with Chachafruto / Basul (Erythrina edulis) to meet the 30 euro minimum and placed an order.

Finally I found it. I remember seeing this dioscorea long ago and put in my wish list but couldn't remember the name, thanks!
Is that price for 1 bulbil or 10? Because they say each packet is 10 seeds, but doesn't say how many bulbils, if same.

EDIT
Just noticed by searching the forum, that you were the one reviewing the plant. Why are you buying from another source?
Hoping for diversity?

EDIT 2
Where can I find one this huge and with this unusual shape? Is it another species?

I think it was for 3 bulbils, probably 'cause they're not technically seeds.

Yes, diversity. There's a lot of variety in D. bulbifera (and in each of the other Dioscoreas). Because it's so rare over here, I've made it my mission to obtain as many edible accessions of Air Potato as I can. It shouldn't be so hard to find a good edible foodstuff like this one, especially one so productive, so I will do my part to make it more common and readily available.

The angled varieties are all of African descent. I call the African ones "D. latifolia" to distinguish them, but that's an old non-valid botanical name for them; they truly are D. bulbifera. According to the link I posted for TYATP, the Asian bulbiferas are superior in taste to the African types, and far exceed them in productivity as well. I still think the African ones are worthwhile, and am seeking them out; I haven't found any so far, though. Las Cañadas has them, but they don't ship outside of Mexico (if any forum member from Mexico is able and willing to obtain and ship them, pm me please).

Ironically, from what I can tell, the African bulbiferas are far more common in cultivation here in the west, yet they've been very hard for me to find. Meanwhile, the edible Asian types are almost unheard of here, yet I've been able to find one or two sources for them. There are several African types (each with multiple cultivars), but I can't really tell them apart... I think some have sharper angles than others. The edible Asian types fall into two main categories (also with multiple cultivars): Sativa and Suavior. If it were up to me, I'd get them all!

But are there asian varieties as big as the african? The african seem much bigger in all the pictures I saw.
I'd rather have something inferior that I can use easily that something superior but easily become a hassle because I have to peel many small tubers to have a reasonable meal.
I think that's also the main reason you see more in the west, we usually don't have much patience :D

It's variable on both counts. I think the largest of the large are African, but the Asian varieties I've seen are fairly decent sized, like a moderately-sized potato. I wouldn't think them a hassle to handle at all at such sizes (if you were thinking polystachya size, I can see how peeling would be a problem - though polystachya doesn't require it). The size difference is small enough, that I wouldn't consider it a factor when comparing the different types. I would think that the angles would make for a tougher peeling experience.

Yearling vines always put out small bulbils. Only from the second year onwards are they supposed to consistently produce the larger bulbils.

This is a bad news. How cold hardy are these for the aerial part and for the ryzhome?
If the aerial part die every year it won't ever grow big aerial tubers?
Title: Re: The Yam Checklist: Starting a Backyard Dioscorea Germplasm Collection
Post by: Caesar on July 20, 2018, 02:23:59 PM
The aerial part dies back every year without fail, as an annual. The underground tuber is the perennial part. No idea how cold-hardy it is, though. If you're concerned about tuber survival, just dig up the tuber and re-plant it whole after the cold has passed. That's how I handled mine on first harvest (for other reasons), and they're doing fine, growing much more vigorously than last year.

From the looks of things, that's a medicinal type, not an edible one. Like the ones on eBay. I wouldn't trust it. Bulbifera isn't like hispida or the other famine food yams... If you get a toxic type, processing it won't leach out the - very potent - toxins (that only works on the semi-toxic types, which shouldn't even be grown in my opinion, given the variety of bulbifera cultivars that lack that toxicity).

Interesting, I've seen purple Asian types, but I hadn't seen a purple African type before (though I had read about it). They seem to cook it with the skin, and in some cases even eat the skin. I had thought the skin was inedible.

Also, to clarify something said earlier, Grower Jim hasn't been contacted (just referenced), the contact is someone else. As for Jim, he doesn't seem to sell bulbifera on his site, but he might be worth trying.

Well, my D. pentaphylla bulbils finally arrived in the mail and I am thoroughly satisfied. I'm obviously still concerned (it's not safe until I see some proper new growth), but they arrived very well packaged and in excellent condition, sprouted and alive! They still don't have leaves, but the very fuzzy stem (a characteristic of their subgenus) indicates that they are in-fact the real deal. I recommend this seller, they were helpful when contacted and they've sent a good product. They said that they don't eat the bulbils (no confirmation of toxicity), but that the tuber is eaten steamed.

One of the slips had fallen off the bulbil, and I accidentally knocked off a second one (with very little effort) but the third was intact. The two slips were treated with rooting hormone to give them an extra boost, and all three of them (plus the now-soft slipless bulbils) were temporarily planted in a tall-ish pot, completely covering the shoots with soil to allow them to acclimate to the local humidity. If bulbil production is low this season, I'll probably just propagate them, but if there's a surplus, I'll add it to my stock.

In other news, the Elephant-foot Yam bulblets (Amorphophallus paeoniifolius) arrived a couple of days ago, and I planted them in small pots to fully sprout them. I have been soaking the Ensete ventricosum seeds since Friday (changing the water mornings and evenings), and planted one yesterday; I'll keep soaking them until this Friday (following the example of another person who had success with them), planting out one seed per day in the meantime, to hedge my bets against the possibility of excessive soaking. And finally, my Ube is resprouting from the stump, so it looks like that was the way to go! Once it starts growing a little more vigorously again, I'll plant it back in the tote where I had it in the first place, next to the Florido yam.

The Ube:

You need to send him a whatsapp message, cause they are not on the website(mobile number is on the bottom).
I paid 31 usd for 5 small bulbils and 1 big sent in 2 packages. Sent in one package was around 20 usd, but the big one is going to attract more attention so I preferred to ship it separately.

Was the root large or rather small? I'm finding it hard to place with what I'm seeing, but I have a suspicion that it might be D. esculenta ("S" twist, prickly stem, alternating mature leaves, potato-like clusters of tubers at harvest). The prickles reminded me of my D. rotundata, but the leaves and stem look different. "Mountain Yam" should refer to the three temperate climate species (polystachya, japonica, hamiltonii), but common names aren't always trustworthy, and the anatomy in the photos contradicts all three of those. D. nummularia has a prickly base, but also paired mature leaves and a "Z" twist, so I'm not sure; the twist isn't visible in this photo, and the leaves are from the stem base, so their current configuration might not be reliable. For now, it might be an esculenta. By all means, keep the photos coming, I'm very intrigued.

The African bulbiferas are on their way, and the Asian ones I got from "Rare Palm Seeds" arrived at my sister's house with the Erythrina edulis (I haven't seen them in person yet). 11 bulbils (and 11 Chachafruto seeds), but judging by the photos my sister sent, they don't look much like bulbiferas... The stems look a bit square and the appearance of the bulbils is a bit off. I'll be documenting everything, and if the anatomy corresponds with something else as it grows, I'll be letting the company know. I don't mind growing extra yams, but I'm already up to my neck in alatas, I don't really need more of those (even the purple Ube sprouted back nicely). I found a feral one growing out back from a bulbil (yellowish flesh, purple-tinged stems), and I stuck it in the Florido's tub. Which reminds me...

I finally found someone to help clear the back hillside! Progress is smooth, if a bit slow. When the work is finished, I'll be planting the area with everything I can find. Root crops, N-fixers, soil stabilizers, Plantains, Yams, Sweet Potatoes (which will help as a ground-cover), and of course, my long-suffering potted fruit trees. I have a few Calliandra calothyrsus seeds saved over from my stint in Utuado university, and I'll probably use them to stabilize a drop-off (caused by a machine fixing an electrical post). I'm thinking of getting some sterile Comfrey to help with the soil building, and I'll probably be using some of my Chachafruto trees for chop-n-drop. I'll be using the path left by the machine for a breeding experiment, which leads me to...

Potatoes! I've tried to grow the store-bought yellow potatoes for years, but even if I chit them, they always rot. I tried a red-skinned and a blue-skinned tuber a few weeks ago, and I finally have a healthy-growing plant in the Florido tub! I don't expect heavy yields, but I'll be satisfied if I get anything. Regarding the experiment, I posted about it in another forum, but I placed a request for several diploid potatoes (Skagit Valley Gold, DTO-2, DTO-28, RN27.01 and M6) to the US National Plant Germplasm System, and they're preparing the in-vitro plants to ship to me (plus some S. cardiophyllum & S. ehrenbergii seeds for good measure). I'll be using them to breed potatoes for the tropics (SVG is disease resistant and maybe heat tolerant, the DTO's are heat tolerant, the RN is purplish-red and super-high in antioxidants, and M6 is a toxic but self-fertile S. chacoense - and if I use it as the pollen parent, there should be no concern of cytoplasmic male sterility; the other two will be bred separately as another edible potato species, although I will be mixing some with the rest of my Phurejas).

Finally, my Hodgsonia macrocarpa seeds arrived, and I've planted them in their own tub (I'll give them their own post of they sprout), with the newly finished trellis! They'll be sharing that trellis with the D. polystachya (I found a survivor!), and possibly with the newer yams.

Very strange, for me they sprout even from some small peel in the compost.
If you let the potato sit at room temperature without soil it will start to sprout by itself, they really need no care.

Where did you get your Hodgsonia? I have some seeds coming from Roy-Ind.

Sprouting the potatoes has never been a problem for me, even the yellow ones. But regardless of whether I planted them sprouted or not, they would always end up rotting. I think it might be the heat. The red ones are said to grow better here anyway.

My Hodgsonia was from Roy as well. I hope to get at least one male and one female to flowering age, otherwise I'll neither be able to taste nor multiply them (the latter being more important than the former, for now).

Did my purple yam post start you down this road? :)


It was a catalyst. I had already decided on acquiring the Ube, and I was already reviewing my yam collection at the moment and looking over the literature, but your post reminded me, so I went to eBay in search of it. And that was all it took... First the Ube, then I went in search of the rest. So thank you!  ;)

I was also reviewing staple crops and have been checking out perennials in the permaculture literature, thus my emphasis on the Air Potato. And in one such article (link here (https://permaculturenews.org/2012/02/25/perennial-staple-crops-of-the-world/)), they also mentioned Mesquite as a highly productive perennial staple. Furthermore, in the comments of a separate article (link here (https://permaculturenews.org/2015/03/16/support-species-for-a-dryland-food-forest-a-practical-example/)), they mentioned Prosopis pallida, P. glandulosa, P. velutina, P. cineraria, and especially P. alba as being the most palatable species, with P. alba being sweeter, non-thorny, non-invasive, and being superior animal forage. Well wouldn't you know it, soon after reading this, I found Rare Palm Seeds was selling seeds of a superior selection of P. alba (link here (http://www.rarepalmseeds.com/fruit_trees.shtml), description here (http://www.rarepalmseeds.com/pix/ProCar.shtml)). I hope to be able to acquire seeds of it while they still have it in stock. I may have to make a separate thread for staples. I'm actually hoping to have a good set of crops to keep myself fed without depending on the supermarket (more like self-reliance than full-on survivalism). I feel the topic deserves to be explored. But for now, I'll focus on the yam collection. ;D

Very nice! It still seems a bit soon to tell, but it looks like they have alternate leaves and are twining with an "S" twist. That, coupled with the spines and the very rounded leaves suggest D. esculenta. If that is the case, you should expect a potato-like cluster of tubers at harvest. Keep it coming, let's see where this goes!
Title: Re: The Yam Checklist: Starting a Backyard Dioscorea Germplasm Collection
Post by: Caesar on August 20, 2018, 04:38:44 PM
Well, I've got an important update, so listen up! The Dioscorea from RarePalmSeeds is mislabeled. From the looks of things, they just don't know any better. As a distributor, they count on their providers to give them the proper identification on the product listed (and let's face it: D. bulbifera is one of the most misidentified Dioscorea in commerce). Having grown them out for 15 days, it's clear that the yam they're selling is NOT D. bulbifera by any means. The anatomy most closely corresponds with D. alata... And I'm almost getting sick of that species. I've received it three times by mistake from different sources, not to mention the two domestic (and one feral) varieties I was already growing deliberately. I don't need any more of these! Please label your yams properly! I have asked for a refund... Time will tell if they'll acquiesce.

Pictures of the yam in question:

The last surviving Pentaphylla yam (and seemingly accurate in its ID) has died. As the tuber was rotting away before the vine died, I don't expect it to resprout. I could order more from eBay, but I get the feeling they're all in a precarious sprouted state, so I will wait for next year, in the hopes of getting them earlier, prior to sprouting. I'll be trying the same vendor again, as they packaged it properly.

And finally, the Elephant-foot Yam (Amorphophallus paeoniifolius) has sprouted! Not really a Dioscorea, but I'm keen on trying it out anyway. I got three pieces, and I had split one into two (and those are the ones sprouting). Photo here:

Where did you take yours? Mine from Ebay user goodmice also arrived rotten and the shipment was delivered in around 2 weeks, so not much.

Mine was from goodmice, but they arrived in fair condition. Sprouted, but alive (though pale white). The tubers fell off from two of the three, but only one of the tubers was bad. Both tubers rotted away. The good tuber on the plant that kept it rotted away recently. I mishandled them: I thought they required acclimation to local humidity levels, so I buried them deeply. All that did was cut off their sunlight and prevent their growth past soil level. When I realized they wouldn't come up, only the one with the tuber remained, and i dug it up and buried it near the surface, with an exposed new sprout. The sprout ultimately failed to green up and grow. It's dead now.

Of the three D. pseudo-tomentosa, only one bore roots, the other two rotted. And this rooted one has failed to sprout past soil level, so I'm concerned as well. Last time I dug down to it about a week ago, it seemed to have living roots, so I left it alone again. Time will tell.

Really? I thought they weren't really sold commercially in the west.

They may be called yams, but given their family I suspect they're probably closer to Cocoyams in culinary qualities.

How long does it take from small size to a reasonable harvest?

Yes, the store owner said they did get shipped in from India.

Interesting. I had thought that they required moist soil, but they seem to do fine under mesic conditions, maybe irrigation under drier conditions. I wonder if they'd be marketable here in Puerto Rico. We're big on yams, but new stuff can be a challenge to introduce to a reluctant populace, even if it seemingly is good.

Thanks for the vids! I look forward to tasting mine 9 months down the road. I certainly hope mine are decent, they were marketed as edible by the eBay seller (from Florida).

Wow - very informative posts and a lot of hard work you are doing - thanks.
I'm in Mexico and have bought from Las Cañadas. Unfortunately, it takes about 2 weeks for a purchase to reach me because I'm in a somewhat isolated region. Forwarding to you after that would be hard on any product. You could try to contact raulglezruiz who is in Puerto Vallarta and may get things a little faster. I wasn't too impressed with the Las Cañadas packaging either. Everything just wrapped in newspaper so all the plants had dried leaves and stems. I bought the only varieties they were selling - Camote Beauregard which they only sold as a plant and bulbils of what they call 'Papas Voladora' which came as dried up bulbils. Not sure if this is the one you want. If mine survives and you don't find it elsewhere, I can send you some when they are ready.
I've only just begun growing sweet potatoes/yams - until now all from store-bought produce. Some seem much more productive than other but that may be due to the different parts of the garden I planted them in. I'll be comparing them growing in the same area this year. I've also been impressed with the way the plants make good ground cover and spread if you don't put them on a trellis.
I'm a little nervous about those Papas Voladoras as they are considered an invasive plant in many regions. They sound like hard work to control.
Potatoes have been a challenge for me too. Again using store-bought potatoes for seed. This year I bought some of the Las Cañadas Papas Criollo to try. Previously my plants have been fairly large but produced few potatoes and didn't flower very much. Last year I got a reasonable crop but I'm not sure why. I planted them later than usual, in November/December when it is a bit cooler but my soil is also improving each year from the original wasteland it was. Then of course there is the question of variety. I haven't yet figured out how to preserve the potential seed for the next year so don't have any to plant this year.
Here is a 'groundcover' sweet potato I just cleaned up to prepare for this year's planting.

Papa Voladora, that's the one! An African bulbifera, and different than the one I'm getting from South Africa (which is rounder; the one in Las Cañadas seems flatter, maybe more angular). I'm looking to get every edible strain of this species that I can find. Keep me posted on yours, I'm looking forward to seeing how they grow.

As for invasiveness, I don't think there's much cause for concern. The edible types aren't supposed to be as weedy or as vigorous as the toxic types. While I can confirm that all the little bulbils that fell off my vine sprouted where they landed, they were easy to find and pluck or mow down, and none re-sprouted; no survivors.


I'm hoping to capitalize on the ground-covering skills of the sweet potatoes myself, to keep the weeds down. I gotta finish getting rid of the Guinea grass, but after that I'm getting my slips started. I actually found a YouTube video where the guy gets them growing from small pieces of peel! Kitchen scraps! I knew you could grow some Dioscoreas that way, but I never figured it'd work for sweet potatoes. Link here (https://youtu.be/OvyzrmbUAUc).

Papa Criolla sound like a Phureja type, they should be able to take the heat better. Store-bought potatoes don't tuberize well above 85 F, if I remember correctly. Mine already started tuberizing (I had to pile on more soil), but I don't expect much, the summer heat's not quite gone. I haven't sown the Cimatli seeds yet, and the in-vitro clones were a disaster. A few survivors from two varieties, and I don't expect them to last much longer. Like potato seedlings, they all succumbed to damping off. I'm not sure when I'll try again, but I already have ideas to offset the effects of humidity (if the rain lets me; the air was humid even under the roof).

I think it's a common name that could represent 1 or more species. Japanese call their long white yam yamaimo (yama=mountain, imo=yam). I'm not sure if other cultures use the same common name for their native yam as well.

We might be able to identify the mountain yam from pictures, but that common name is very generic, so if it turns out to have an alternative, we should use it.

I’m going to have to try again with a few of them next year. My pentaphylla and pseudo-tomentosa died off, the hamiltonii failed to sprout, and I didn’t reach the business in time to acquire the japonica bulbils. On the bright side, the Ube, the yellow cayennensis and the polystachya are doing just fine. What’s more, the crop on the Indian bulbifera is just starting to take off; more on that in its own thread (http://tropicalfruitforum.com/index.php?topic=26151.0).

My African bulbifera’s arrived sprouted and in excellent condition. I buried them in a small pot for the moment; tomorrow I’ll get another tub ready and place it by the new trellis.

Here’s mine:

Edit: I forgot to mention: the trifida doesn’t play well with others. All the other species are competing for space and growing vigorously (though I’m sure yields will suffer). Meanwhile, the trifidas are failing to put on extensive vine growth, and I don’t expect a good harvest. For anyone growing trifidas out there, give them their space, don’t crowd them.

The Beauregard didn't handle the shipping stress well? How were they packaged? A root might have made the trip in better condition, but I guess they keep the roots as crops and just sell rooted cuttings.

It's great to hear the air potatoes are doing well for you. I think you may be the first person in the forum with that particular cultivar. But "papa voladora" is a pretty generic name, it's just air potato (or "flying potato"), so I think it's safe to assume that this clone is nameless. What would you name it?

My Trifida is also the least vigorous of my varieties. These were from grocery store-bought roots and may have been deteriorated in shipping so my home-grown roots may do better next season.

Also, the purple ube Alata yam I am growing had begun to climb on some other nearby trees and some vines were on the ground.
As I trimmed them back I noticed that vines touching the ground had begun to root at the nodes. This looks like it might be another way of propagation by air layering. So, if you'd like to try I'd suggest using sphagnum moss, coconut fiber, or similar media well moistened and wrapped with aluminum foil at nodes to get new plants.

I'm gonna try that with my Ube, to focus on sending the bulbils to other growers. In fact, I won't be harvesting the tuber for at least a few years. I wanna make the vine grow strong and vigorous, to ramp up its bulbil production.

*

I have saturated myself with projects. The yams are all fine, but my second attempt at in-vitro potatoes for breeding was a disaster, and I didn't get to collect raspberry pollen for my hybrid experiment with the strawberry.

Here are the two surviving in-vitro potatoes, Skagit Valley Gold and Unica. I got the Unica as a tetraploid for reference, the rest were meant to be diploid, but I asked for a lot of tetraploids by mistake. They can be bred together, but them I'd have to rogue out triploids. They're sharing the tub with a pair of DTO varieties and a red phureja. I had poor luck with in-vitros, but I also asked for diploid seed and I expect to have better luck with seedlings, so the project isn't scrapped. The particular seeds are better adapted to my conditions anyway, compared to the in-vitro diploids, so that was a nice surprise.

But anyway, back to the yams. Here we have the base of the pvc trellis, showing everything I got growing around it. In the ground is a Barbados Gooseberry, then one bucket with the Ube one with the Nagaimo Yam, and then the two tubs, one with a struggling set of Hodgsonia + Jarilla, the other with the Sena Air Potato (reposted pic from the other thread). With said air potato are Recao, Mauka, Bambara Groundnut and a recently-planted Striped Peanut (not pictured).

Here's one of the Nagaimo Yams (D. polystachya) which I've since placed in the bucket with the rest. This one took a long time to come up from the roots. In fact, the Nagaimos are always the last to sprout in my yard, it's frustrating.

Some more recent pics of the Ube (note the stem looks slightly less red by now). I twined the Nagaimo over it, so it's a mess of leaves from both species, but the big Ube stem is easy to make out.

Also trying again with D. pentaphylla, same vendor. Before buying, I asked the vendor about the harvest season and if they had fresh bulbils. They did, and they arrived in great shape! This time next year, I'll have Pentaphylla bulbils for distribution. As for dodecaneura, I'll have to figure out how to propagate it... Maybe layering?

I ordered a Dioscorea dodecaneura/discolor from this place: link (https://almostedenplants.com/shopping/products/3128-variegated-monkey-ball-vine-ornamental-yam-variegated-potato-vine/). It'll be shipped next week, and I suspect it'll arrive before week's end.

Also trying again with D. pentaphylla, same vendor. Before buying, I asked the vendor about the harvest season and if they had fresh bulbils. They did, and they arrived in great shape! This time next year, I'll have Pentaphylla bulbils for distribution. As for dodecaneura, I'll have to figure out how to propagate it... Maybe layering?

This ones are edible? I never saw them...  ;D

The Five-leaf Yam has edible and poisonous varieties. This one is being sold as edible, and the vendor eats them steamed. She also said she doesn't eat the bulbils, but couldn't explicitly confirm if they were toxic or merely ignored by the people. I'd like to cook a bulbil sample when they start producing and send it to a laboratory for analysis, but I haven't found a local lab yet that could analyze it.


And here are the two dioscorea bulbifera bulbs that i got from Cesar. They are big... 250g each and will be planted next spring!  ;D

I'm glad they arrived in good condition! I was a bit worried, this was my first time shipping international. But it looks like they had no trouble.

In the audio and text description it sounds like they're referring to several different species. The species shown looks like an alata. Interesting how different species are used in different ways depending on where you are.
