I think that may be Meiogyne cylindrocarpa

Looks correct to me.

It's funny to me but I'm starting to see a very few people that have the same opinion as I concerning small tasting gatherings rating the best tasting mango. Usually the "wow" mango wins with intense taste with the small amount sampled during the sampling...

IMO many of these "wow" small servings would not be desired by me in a cut up bowl of 3-4 mangos eaten in a day as taste overload would occur. It sort of reminds me of the "wow" taste of Monstera Deliciosa that has a strong pineapple/banana taste on the first few sampling pieces, but it's no way I could stand to eat two whole pods in a sitting. Thus my list of mangos tried this year:::

1st place: Keitt - Great peachy sugar flavor especially the 2nd or 3rd day in the refrigerator it becomes almost sugar if cut up ripe. I can eat many of these in a day with no problems and no desire to stop...

2nd place: Carrie- Long season from May 8 to 8.22.17 with one left on one tree. Great flavor that I have grown to love. (if too strong try eating from bottom and rinsing off peeling sap).

3rd place: multiple ties: Edward, Rosigold, Kent, Glen (a few were equal to Rosigolds), Sweet Tart (a small slice of "wow" factor to break up the usual mango taste of this category), Madem Francis was sweet this year and made the spicy flavor taste like pumpkin/sweet potato pie although a lot of fiber in it,  Phillipean moved up this year as very sweet and lemon/lime taste when biting off the bottom and mixing the peeling taste with the sweet juice, a few of the Valencia Pride,

4th place: Mallika, Pickering, Haden, Kesar (young tree), Spirit of 76 (young tree), unfortunately Florigon was less sweet and less flavor and smaller harvest than last year.

5th place: Okrung was too early producer and low production with little sweet/lime flavor this year compared to last, Tebow aka Young low production and less flavor also this year,

Tropical Fruit Discussion / mangosteen germination
« Last post by dingaling on Today at 12:33:26 PM »
Gday,

 I am lucky enough to work in an area that has plenty of Purple Mangosteen fruit available. Supporting the local people in their small market I have in the past ordered 20kg of mangosteen and eaten them all in a matter of a week or so. I was collecting the seeds to take back to Oz to plant in our garden. This I have done with no issues from customs at the airport as long as they are declared and clean I haven't had any problems. The only issue is that they are normally sprouted quite long by the time I get home and I think this might weaken the seedling but I am not 100% sure about this. Anyhow back to the story, last trip in to work I purchased 6kgs of fruit in Vientiane and ate them upon arrival to site 5 hrs later. I put the seeds in some 2nd hand vermiculite that I had in the cupboard from where I had brought some Z4 abiu seed over for the lads here at work who are mostly slash and burn type rice farmers. I put the seeds back into the cupboard and completely forgot about them. I worked for my roster of 4 weeks and then went on break for 2 weeks back to Oz. When I got back to site next time I found the seeds in the cupboard and they were still alive. See attached pics. The shoots were very long but they were still very much alive. Tough these little buggers!







 I have found that I don't have any issues with mould because we clean the seeds properly as we are eating the fruit. Because we have had so many fruit I have been very rough with the seeds and found that sort of chewing the skin off the seed once the fruit has been eaten off it works the best and you can get quite rough. Sometimes the seed will crack in half but if the complete skin is not removed we have trouble with mould. Take all the brown skin off if possible and just leave the creamy colour seed, put it in a clip lock bag with just a touch of moisture in there and away you go. With this method we have been getting around 90% and more germination of the seeds with no mould issues.

Well yes I may be jumping to conclusions.

I am not trying to praise myself at all but most people do not care for their trees and a 4 x4 tree size is the same thing you will find here on many occasions, usually caused by letting it fruit as a damn twig.  No mulch, weeds, grass to the trunk area, improper fertilizing or forgetting to fertilize altogether are common problems. It's all common sense!  It reached 10 ft at well under 3 years actually.  8-4-8 fertilizer works great but I also give them Ironite at equal ratios depending, with every feeding. And another big thing is over watering when people fertilize! they push the fertilizer past the root zone which is a common practice in our sandy soil and the trees get little fertilization.  Sorry for hijacking, but wanted to respond! I will post a pic later that I take today.

Cold Hardy Citrus / Re: breeding cold hardy pomelo
« Last post by SoCal2warm on Today at 12:20:17 PM »
Wonder what the cold hardiness of a Valentine pummelo is compared to other pummelo varieties.  I ask this because Valentine is not a true pummelo, it is a hybrid of pummelo and a blood orange.
I don't think blood oranges are very cold hardy. I've also noticed that hybrids between different citrus species often show slightly less cold tolerance than their parents (and may be slightly less resilient in general). I think it's a mild form of what is known as outbreeding depression.

Awesome, thanks for that information.  I'm definitely curious to see what the fruit will be like, but cold hardiness is probably the most important thing for me. I'm zone 10a/9b so the hardiness is definitely a huge factor for me.

Tropical Fruit Discussion / longan
« Last post by dingaling on Today at 12:09:27 PM »
Our Longan has finally flowered. Its is a grafted variety but I am not sure what variety. It has been in the ground for about 5 years and we were giving up hope thinking that Darwin just doesn't get the chill that is required to get them to flower. I spoke to a gardening friend     (Chris N for those in the know) and he put me onto the bleach theory. So about 4 months ago I poured about 4 bottles of woollies finest bleach just out past the drip line (I think they are 2 litre bottles). Was very pleasantly surprised to see these flowers bloom. Possibly just a fluke and it was going to flower anyhow.................. who knows.

 Couple of very very nice looking Rollinia fruit coming on as well. 2 different trees from the same batch of seeds and the fruit on one tree are nice and smooth, the other just a touch of the spiky appearance. The fella who gave me the seeds (from QLD) will know who he is and a big thank you is going out to him for these cracking fruit. Hope they taste as good as they look.

Cold Hardy Citrus / Re: citrus varieties in order of cold-hardiness
« Last post by SoCal2warm on Today at 12:02:32 PM »
From some sources, I've read that (or at least seen indication of) Ichang papeda is only very slightly cold-hardier than yuzu.
In other words, Ichang papeda may be slightly less cold-hardy than commonly thought (at least under some conditions it seems) and yuzu can be more cold-hardy than commonly thought. These two are very closely related I think, closer than people realize (I think the story might be a bit more complicated than yuzu being a simple one-time hybrid cross, but that's my perspective).

The information I've come across has commonly indicated that yuzu is a little bit more cold-hardy than Changsha, but I don't really know if that's the case. They could be about equal, or Changsha might be ever slightly more cold-hardy in some situations. We have rough values for the temperatures these citruses can survive but it's hard to ascribe more precise values that are completely accurate to within 5 degrees F. I have never seen an experiment where several trees of each of these were compared with each other right around the critical cold temperature and where one type survived and one did not. Or I mean where one group clearly outperformed another group, with multiple trees from each group.

It almost seems like Ichang papeda may be able to survive lower temperature in absolute terms, but Changsha (and to a slightly lesser extent yuzu) has a better ability to bounce back after some cold damage and shows more resiliency. It also seems like yuzu has better ability to tolerate late freezes and fluctuating temperatures than trifoliate, even though trifoliate definitely can survive much lower temperatures in absolute terms.

Also wanted to mention here that Changsha mandarin shows the trait of being very drought tolerant as well.

I don't know, if I had to guess I'd guess yuzu is probably about 3 or 3.5 degrees (F) more cold hardy than Changsha.
But if you're thinking about breeding cold hardy citrus, it might be easier to breed something edible from Changsha though, because Dr. Brown's two yuzu-clementine crosses didn't turn out that good, had some bitterness and kerosene smell; whereas the Changsha-Satsuma cross called "Orange Frost" has very good fruit quality. Yuzu might theoretically be more optimal to start off with, but it would probably take several more successive generations to breed out the undesirable attributes. Or it just might be that yuzu would be more appropriate if you were trying to breed something like a lemon.
