Title: Wanted: Temperate Eriobotrya species - East Asia
Post by: Patanax on October 25, 2018, 06:20:09 PM
Hello,

I am looking for seeds of temperate climate Eriobotrya species, so relatives of Eriobotrya japonica (Loquat).

I've come across this interesting paper on breeding loquats:
https://hort.purdue.edu/newcrop/pdfs/breeding-loquat-pbr37.pdf

On page 11 and 12 they talk about the possibility of using wild Loquat species as rootstock for commercial Loquat production and mention Eriobotrya fragrans as an even cold-hardier species than japonica, although the native distribution area in Guangdong makes this seem unlikely? Anybody who lives in a colder climate in East Asia and wants to send me some seeds of Loquat relatives? Buy or trade.

I'm also interested in that too, for temperate species of that genus.

So I made a non-scientific list of some Eriobotrya species and their USDA hardiness zones, based on sources I found online. So far it looks like E. fragrans would be the most promising species in terms of hardiness.

USDA Zone 5? Foreal?

Post by: NateTheGreat on November 21, 2018, 12:37:47 AM
Yeah that doesn't look right. Why would it be 5/8/9... and not 5/6/7/8/9...? It looks like they're native to the mountainous southern China and northern Vietnam at around 850m. From what I've read that area doesn't get that cold, probably somewhere around -2 C or so annual low. From what I've read loquat (japonica) grows in Seattle, but only sometimes sets fruit there, and that's 8b, almost 9a. If I were you, I'd be looking for one with a native range farther north. Seems like Eriobotrya hookeriana or Eriobotrya petiolata might have potential, as they're from the eastern Himalayas. I see hookeriana is reported to grow in a city called Trongsa. From the climate data there: https://weatherspark.com/y/111894/Average-Weather-in-Trongsa-Bhutan-Year-Round it looks like they dip into the teens (F), so maybe like -8C? It can probably take a bit below that, but maybe not 14C, to get to 7a.

If you're just looking for rootstock, quince works and is hardy below 7a, but from what I've read the loquat flowers wouldn't set fruit if they freeze.

Well, I made the list using the two sites below, one being a book with some Eriobotrya species and their distribution in China (not neighboring countries) and the other being a USDA zone map of China. I couldn't find any ready-to-use zone information for most species (other than japonica and deflexa), probably because those species aren't being cultivated outside their native range.

If you look at the uppermost left spot for E. fragrans in the book and compare it to the zone map, that area is supposedly zone 5. The rest of its native distribution area is zone 8+ though, so I didn't write the zones inbetween.

Established E. japonica trees are hardy to about 12°F (-11°C), so zone 8a. According to the paper from my first post, E. fragrans is hardier than japonica. Probably not zone 5 though.

Regarding fruit in colder climates, at least E. japonica, the regular loquat, has an unusual flowering habit in that they flower in fall and bear fruit in spring. So in any area that has temperatures below about 27°F (-3°C) in winter, fruit is unlikely. But you can still grow the plants themselves, e.g. as evergreen ornamental. In the best case, there would be a hardier relative of japonica that flowers in spring and bears edible fruits in fall. But I would be happy with anything that is a bit hardier than japonica, so that I could attempt growing it in zone 7 with protection.

The paper mentions quince rootstock on page 11, stating that is is mostly used for its dwarfing effects in commercial fruit production but that it isn't compatible with all varieties and leads to zinc deficiency in the plant. Do you think it would make the trees hardier? Aren't they more resistant to the cold on their own roots?

Also, thanks for the suggestions, I'll have to look up E. hookeriana and E. petiolata :D

Some information about Eriobotrya elliptica and hookeriana in (Nepal):
http://www.floraofnepal.org/onlineflora?wildcard=10149 (http://www.floraofnepal.org/onlineflora?wildcard=10149)
http://www.floraofnepal.org/onlineflora?wildcard=12672 (http://www.floraofnepal.org/onlineflora?wildcard=12672)

And in comparison the hardiness zones of Nepal. https://davisla.files.wordpress.com/2013/10/india-pakistan-bangladesh-nepal-plant-hardiness-zone-map.jpg (https://davisla.files.wordpress.com/2013/10/india-pakistan-bangladesh-nepal-plant-hardiness-zone-map.jpg)
Both of them can also be found in the north of the country, where the hardiness zone is 6.
So Eriobotrya elliptica, fragrans and hookeriana should be a good choice. But I have no idea when they flower and fruit.
The other problem is, where do we get those species? The area where E.fragrans occurs in zone 5 (China) is not that populated.
For the species of nepal, I wrote to a nursery in Patlekhet, Nepal, but until now they have not responded.

I have overlooked the flowering and fruiting time, sorry.
E.hookeriana flowers october-november and fruits march-june. Whereas E.elliptica flowers in april and fruits in june.
So E.elliptica would be the better option. Or is hookeriana better? I think it depends on how frost hardy the flowers are and if the frost risk in your area is higher from october to november or in april.
With regard to E.fragrans, I don`t know anything about flowering or fruiting time.

 I found a few japonica plants over the last years around here in northern Germany. Cold hardiness seems to be fair enough. Just some weeks ago I found a small tree in a village nearby. The owner told me it is around 8 years old.
In the yard of the town house here in Luneburg there were real trees up to 3-4 m high until 2 years ago when they were cut down.
We are in USDA zone 7.
What is missing is a variety which flowers in late spring. E. elliptica sounds interesting.
I was thinking about an hybrid variety called "coppertone". Might be different? Any experience?

Nice to hear about the Eriobotrya japonica trees doing well in zone 7(a). Some resources say that they are just hardy until zone 8(a), but I think older plants will be hardy until Zone 7.
The hybrid called Eriobotrya 'Coppertone' is a hybrid between Eriobotrya deflexa and the Indian hawthorn (Rhaphiolepis indica), so not a true Eriobotrya. Coppertone is said to be cold hardy until Zone 8a, but the advantage is that the bloom is in spring. The fruits are also edible. E.deflexa is a really bad crossing partner if you want a cold hardy hybrid, because it is distributed in warm zones like 9, 10 and 11. https://books.google.at/books?id=rXTGyOlDjdoC&pg=PA515&fbclid=IwAR2gcYSS6BvPlgO1ytIFTjMpiw5bpHaxV-DJD_yWYoyHLE0rgRwb_1eYQlU#v=onepage&q&f=true
Some also say that Coppertone is a hybrid between E.japonica and Rhaphiolepsis indica. (What would be a bit better, because E.japonica is hardier).
Rhaphiolepsis indica itself is hardy until zone 7(a) or 8(a) (statements vary).
All a bit cold hardy, but nothing really hardy. A Coppertone hybrid (with E.japonica in it) could be worth a try. But if we could get our hands on species like Eriobotrya fragrans, elliptica or hookeriana, that would be a real game changer.

Post by: NateTheGreat on November 29, 2018, 11:35:23 AM
There are a lot of the 'coppertone's planted in my area. They're usually called bronze loquat out here. They're also called fruitless loquats I think. I think they have very small fruits, with barely any flesh. I'm not certain, but they're certainly not something I ever thought had potential as an edible.

Edit: Maybe coppertone and bronze are different. I believe these are a hybrid with R. indica, not sure with which Eriobotrya species.

Hello, sorry for the late answer, I didn't have time up until now.

@Mangifera08

Unfortunately, it seems that E. Elliptica is not very hardy. I found a paper about a specimen in the Kew Royal Botanical Gardens in London with lots of information. They mention that it is too frost-tender for a cultivation in Britain, which is an important information considering that the regular loquat, E. japonica, is hardy through most of the UK (according to the Royal Horticultural Society).

E. fragrans flowers in Apr–May and fruits in Aug–Sep.
E. petiolata, which was mentioned earlier, flowers in March-May.

@mikkel

In January I also found a several years old loquat at a community garden in Vienna. Unfortunately, when I came back to take a look at it again in summer, they had cut it down because it got too big for the limitations in the community garden and had never borne fruit...

https://imgur.com/a/jiAdZ2S (https://imgur.com/a/jiAdZ2S)

The winters in the city are definitely milder by a few degrees though.

I've heard of "Coppertone", but there are various sources giving different information. Many nurseries seem to either sell a regular E. japonica cultivar under the name Coppertone or have mixed up their description text and pictures with E. japonica. For Coppertone, you can find everything from "flowers in fall and bears edible fruit in spring" to "flowers in spring but doesn't form fruit at all".

I found this paper, but it is also very vague. It doesn't mention the flowering time but says that Coppertone doesn't form fruit at all. Anybody who can confirm/deny this?

https://www.researchgate.net/publication/253330818_An_intergeneric_hybrid_between_Eriobotrya_and_Rhaphiolepis (https://www.researchgate.net/publication/253330818_An_intergeneric_hybrid_between_Eriobotrya_and_Rhaphiolepis)

E. deflexa itself isn't very hardy though, so even if Coppertone is a bit hardier because of its other parent (most likely R. indica?), I doubt it would do well in colder climates.

@NateTheGreat
Bronze loquat is the common name for E. deflexa. Coppertone is a hybrid, most likely between E. deflexa and Rhaphiolepis indica.

Yes it seems like the individual plant at Kew is not at all hardy. But in the paper they mention:„Seeds were gathered by him at Phulchoke, to the south-southeast of Kathmandu on the road from Lalitpur, due east of Godawari.” (Which, I think is hardiness zone 8 or 9).
What I think is really strange is that it just can tolerate temperatures down to 7 °C (44,6 °F). That would be even to frost tender for zone 10. (The warmest hardiness zone in Nepal).
But how I wrote earlier, the species is distributed in different hardiness zones, even in hardiness zone 6. http://www.floraofnepal.org/onlineflora?wildcard=10149 (http://www.floraofnepal.org/onlineflora?wildcard=10149)
If you take seeds from a individual in the north (hardiness zone 6), the plant should grow well in zone 7.
Thank you very much for the flowering and fruiting information for E.fragrans and petiolata, but unfortunately I cant open the first link.(That one: http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200010832 (http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200010832))

Good point @Mangifera08, I had not considered the possibility that it could just be a specimen from the warmer regions and not represent the full hardiness potential of E. Elliptica. After all, they talk about the same thing for E. japonica cultivars in the Breeding Loquats paper on page 10.

The link works fine for me. Maybe try another browser or disable some browser extensions? Here is a screenshot of the page: https://imgur.com/a/kQkp5Fo

Thank you very much for the screenshot, since I tried to open it with another browser, but it doesn`t work. Thanks for mentioning this page of the paper. I thought that every older loquat would do fine in zone 7, especially if it is crossed with another hardier species. (Maybe they do, if they have a very hardy crossing partner). But in case you want to breed a Eriobotrya, that is as hardy as possible, you should also choose a Loquat cultivar, which is as hardy as possible.

Great news, it appears I am not the only one who had this idea. There is very recent research into producing loquat hybrids to shift the flowering period into spring and create more cold hardy specimen which "could even enlarge the cultivated area of loquats" :D

Identification of interspecific hybrids between loquat (E. japonica) and bengal loquat (E. bengalensis)
https://www.pakbs.org/pjbot/papers/1497347472.pdf (https://www.pakbs.org/pjbot/papers/1497347472.pdf)

As this paper is only from last year, the trees haven't yet grown up and flowered or born fruit. So the results are still unkown. Perhaps we will see new hybrid cultivars from this breeding effort in the coming years. Pretty exciting to be so up-to-date with current research ;D

In combination with the many hybrids that were mentioned in the paper @mikkel linked, development seems pretty promising.

I also found a paper about natural hybridization between E. japonica and E. prinoides. Unfortunately, E. prinoides also flowers in winter, which is why they could hybridize naturally in the first place, but which also makes it less suitable for cultivation in colder climates.

japanese genebank NARO has several accessions of Eriobotrya. if there is no import restriction they can send worldwide.

You can make a request for certain plants and BGCI sends your request to botanical gardens that have this plant in their collection. If a botanical garden is interested, they can contact you via email. I haven't used the BGCI website before, I only found them via Google.

I have five seedling loquats (E. Japonica) that I could use as rootstock. I could also buy a quince from a local nursery. But if the two listed botanical gardens that have those species are located in Asia, seeds are probably the only way. I don't think shipping scions from e.g. China to Austria would work out.

But I need to get a reply first 😅

So I wrote the corresponding author of the paper "Identification of interspecific hybrids between loquat (E. japonica) and bengal loquat (E. bengalensis)" and asked him about the progress of the project. While he is already working in another area, he sent me a link to a news article.

Apparently the hybrid trees mentioned in the paper have already flowered and fruited twice and produced tasty loquats. From what I've understood via Google/Bing Translate, they flower in March (the text also mentions April?) and produce fruit in June. Their current temporary cultivar name is "Spring Blossoms" loquat ('春花'枇杷) and the trees are located at the scientific research park of Sichuan Agricultural University. The team is currently trying to graft them on regular loquat cultivars. Can anybody who speaks Chinese confirm (regarding April)?

So I guess there are spring-blooming loquats now :D

Well, their growing season is longer. Maybe they would start flowering later in other areas if it's still cold there in March? The question is also how hardy those hybrids are. E. bengalensis is a zone 9 plant from what I can see. Maybe you could cross back to E. Japonica while keeping the spring-blooming habit? It would also be interesting to try a similar cross with one of the cold-hardier spring-blooming species (E. fragrans, E. elliptica, E. petiolata).

@Patanax
Yes, maybe they would flower later if it would be to cold in march. I haven`t thought about this. But maybe if there would be a warm and sunny period for a few weeks in march, they would think: „Oh, the winter is over, the cold temperatures are gone”, and would start flowering. These flowers would then get completely destroyed, when the warmer weeks would be over, and it would get cold again.
Yes, the hardiness would be the next difficulty. This hybrid is maybe not hardy enough. (Since it`s probably a cross of a subtropical/southern group cultivar with E. bengalensis). Backcrossing with E. japonica is maybe not such a good idea, because all E. japonica flower in winter. So the cross would probably flower in between the two parents, therefore in February or so. (The flowering time would be developed in the false direction). On the opposite a backcross with E. fragrans or E. elliptica would be a good idea. (By the way, what do you mean with: „It would also be interesting to try a similar cross with one of the cold-hardier spring-blooming species”? Do you mean to cross E. japonica with one of the cold hardy species, or do you mean to cross the Spring Blossoms hybrid (japonica x bengalensis) with one of the cold hardy species?)
And one last question, do you know how he was able to accomplish that his hybrid flowers in march? (Since E. bengalensis flowers Nov-Feb, and E. japonica normally flowers in late autumn or winter). Did he selected the hybrids for late blooming?

@mikkel thank you for your information, E. fulvicoma (zone 10) is even less hardier then E. bengalensis (zone 9), but the late flowering is definitely a trade, that makes this species very attractive for crossing with other species.

It seems Eriobotrya species beside japonica are very rare. I made an request via bgci one species was only available in 2 BG`s an other only at one BG.
It seems nearly impossible to get these species as an amateur gardener.
Just in case does someone ever tried to graft on Crataegus and other rootstocks?

Just in case does someone ever tried to graft on Crataegus and other rootstocks?

The "Breeding loquat" paper lists many different rootstocks for loquat, including Crataegus. Only as "being in evaluation", but that should mean that they are at least somewhat compatible.

Page 5:
"E. deflexa and E. prinoides have been used as rootstock, but they are less widely used than Photinia serrulata Lindl. in China and Cydonia, Malus, Pyrus, and Pyracantha in Mediterranean regions."

Page 11:
"There are reports of other rosaceous species being evaluated as rootstocks for loquat in various countries. These include hawthorn (Crataegus scabrifolia Rehd.), apple (Malus x domestica Borkh.), fire-thorn (Pyracantha fortuneana Roem.), medlar (Mespilus vulgaris Rchb.], pear (Pyrus communis L.), Chinese photinia (Photinia serrulata Lindl.), and quince (Cydonia oblonga Mill.)."

These flowers would then get completely destroyed, when the warmer weeks would be over, and it would get cold again.

Yes, that could happen. We don't know until somebody tries it... :D

This hybrid is maybe not hardy enough. (Since it`s probably a cross of a subtropical/southern group cultivar with E. bengalensis).

Yes, the loquat cultivars that were used for the cross are "Dawuxing" and "4-1-5". Dawuxing is actually listed as the example for the southern cultivar group, which is less hardy than the northern group, in the "Breeding loquat" paper. I can't find any information on the white-fleshed 4-1-5 cultivar though.

Backcrossing with E. japonica is maybe not such a good idea, because all E. japonica flower in winter. So the cross would probably flower in between the two parents, therefore in February or so. (The flowering time would be developed in the false direction). On the opposite a backcross with E. fragrans or E. elliptica would be a good idea.

I don't know how flowering time is regulated in the genes in loquat and what determines if a cross has the flowering time of either one of the parents or a different time altogether, but I wouldn't assume that all crosses would flower in e.g. February as that is the middle between the parents. If that were true, then creating the Spring Blossoms hybrid would not have worked in the first place.

We only want one trait from E. bengalensis, which is its spring-blooming habit. It's less hardy than E. japonica and I don't know if it produces desireable fruit. A backcross with E. japonica would ensure good edibility, better hardiness, and less unrelated E. bengalensis genes. In the offspring between the hybrid and E. japonica there would surely be winter-blooming plants, but the question is if there are still some that flower in the spring. Those would be superior plants, which are even closer to E. japonica while still keeping the valuable spring-blooming habit.

I would not cross the hybrid with other wild relatives which further decreases edibility and deviates from regular loquat. A complex hybrid with many different species and a majority of wild genes doesn't seem neccessary when a first generation hybrid with E. japonica already has the spring-blooming trait. I'd rather cross a northern E. japonica cultivar with E. fragrans, E. elliptica or E. petiolata if I have access to those.

(By the way, what do you mean with: „It would also be interesting to try a similar cross with one of the cold-hardier spring-blooming species”? Do you mean to cross E. japonica with one of the cold hardy species, or do you mean to cross the Spring Blossoms hybrid (japonica x bengalensis) with one of the cold hardy species?)

I meant a cross between E. japonica and another cold-hardy, spring-blooming relative. So e.g. E. japonica x E. fragrans.

And one last question, do you know how he was able to accomplish that his hybrid flowers in march? (Since E. bengalensis flowers Nov-Feb, and E. japonica normally flowers in late autumn or winter). Did he selected the hybrids for late blooming?

I also found sources that state that E. bengalensis flowers in the winter, but according to the paper, they chose E. bengalensis as a hybrid partner for E. japonica particulary because it flowers in the spring. I don't know why e.g. Flora of China states that they flower in the winter... ???

Identification of interspecific hybrids between loquat (Eriobotrya japonica Lindl.) and Bengal loquat (E. bengalensis Hook.), Page 1:
"Bengal loquat (E. bengalensis Hook.) blooms in March and April and ripens in July and August in China, is considered a valuable genetic resource for breeding spring-flowering E. japonica cultivars which can avoid cold injury in winter."

You could be right. Most of them would probably flower in between, but there could be some that flower at a different time.
This could work out. As you said, the fruits, would be even better than from the Spring Blossoms hybrid, because the resulting hybrid would have less E. bengalensis genes.

I would not cross the hybrid with other wild relatives which further decreases edibility and deviates from regular loquat. A complex hybrid with many different species and a majority of wild genes doesn't seem neccessary when a first generation hybrid with E. japonica already has the spring-blooming trait. I'd rather cross a northern E. japonica cultivar with E. fragrans, E. elliptica or E. petiolata if I have access to those.

I have to agree totally. Yes, crossing a nothern E. japonica cultivar with one of the spring blooming cold hardier species, seems to be a far better idea.

I also found sources that state that E. bengalensis flowers in the winter, but according to the paper, they chose E. bengalensis as a hybrid partner for E. japonica particulary because it flowers in the spring. I don't know why e.g. Flora of China states that they flower in the winter... ???

The information about flowering/fruiting of different Eriobotrya species is very confusing. I thought for example that E. japonica always flowers in winter, but Flora of China says that E. japonica flowers in June (and fruits Jul-Aug). I don`t know exactly why, but it seems that the same species in China has a completely other flowering (and fruiting) time in Europe or America. Additonally there comes a difference in flowering time, depending on the (hardiness) zone. The same species probably flowers earlier in the warmer areas of its range. But I don`t think that the zone difference is the only reason for the difference in flowering (,fruiting) time. Therefore it could be, or more likely has to be that other Eriobotrya species planted here, also flower at a different time than Flora of China says.

It talks about the (algerian) Loquat variety called „Piera”, which blooms and ripens fruit throughout the whole year.
This trait could make it possible to grow Loquat in colder zones. I also think that this cultivar could cope with our winters, since it`s a pure E. japonica (not crossed with cold sensitive species like E. bengalensis).
Until now I could not find this cultivar, but if more people search for it, the chance to find it is much higher.

Ok, I have also written a few nurseries in South Tyrol.

The paper states that Piera is a bud mutation of the cultivar 'Algerie'. That's the name of another cultivar, they don't mean the country Algeria. The IVIA website actually has 'Algerie' in their collection as well, but it doesn't have the same flowering properties as 'Piera' so it's not that interesting.

So I wrote the corresponding author of the paper "Identification of interspecific hybrids between loquat (E. japonica) and bengal loquat (E. bengalensis)" and asked him about the progress of the project. While he is already working in another area, he sent me a link to a news article.

Original: https://sichuan.scol.com.cn/yaxw/201806/56299857.html
Google Translate: https://translate.google.at/translate?sl=zh-CN&tl=en&u=https%3A%2F%2Fsichuan.scol.com.cn%2Fyaxw%2F201806%2F56299857.html

Apparently the hybrid trees mentioned in the paper have already flowered and fruited twice and produced tasty loquats. From what I've understood via Google/Bing Translate, they flower in March (the text also mentions April?) and produce fruit in June. Their current temporary cultivar name is "Spring Blossoms" loquat ('春花'枇杷) and the trees are located at the scientific research park of Sichuan Agricultural University. The team is currently trying to graft them on regular loquat cultivars. Can anybody who speaks Chinese confirm (regarding April)?

So I guess there are spring-blooming loquats now :D

Definitely keep us updated on the progress. If you're able to aquire seeds, I'd love to buy some from you :)

Sadly I haven't been able to find a nursery which offers Piera. As the variety is grown in Italy and Spain, I think reaching out to private collectors that are located there and that are growing named varieties would be the best bet.

I will post an update regarding my progress in the next few days.

Post by: Patanax on June 26, 2020, 03:40:23 PM
So here is the promised update :)

Considering that it will probably take a while before I can find a source for wild Eriobotrya species, I've been going through the previous papers and taking notes to get a better picture and to better know what to keep an eye out for. I've also found three new papers which are relevant for this project.

The first one highlights the close relationship between Eriobotrya and Rhaphiolepis, even suggesting that Eriobotrya should be nested within Rhaphiolepis.

Eriobotrya Belongs to Rhaphiolepis (Maleae, Rosaceae): Evidence From Chloroplast Genome and Nuclear Ribosomal DNA Data
https://www.frontiersin.org/articles/10.3389/fpls.2019.01731/full (https://www.frontiersin.org/articles/10.3389/fpls.2019.01731/full)

The second paper seems to confirm this close relationship, as it describes artificial hybrids between Rhaphiolepis and Eriobotrya. After all, the "Coppertone" loquat is most likely also a hybrid between R. indica and E. deflexa.

Possibility of intergeneric hybrids between loquat (Eriobotrya japonica lindl.) and other Rosaceae plants:
https://agris.fao.org/agris-search/search.do?recordID=JP2008008365 (https://agris.fao.org/agris-search/search.do?recordID=JP2008008365)

The third paper is probably the most exciting, as it describes a technique which could enable new combinations when hybridizing different Eriobotrya species. Considering the number of recent Chinese papers that talk about hybridizing wild Eriobotrya species with E. japonica to shift the flowering time to spring, I truly believe that we will see a new generation of spring-flowering loquat cultivars in the coming years.

Cut-style Pollination Can Effectively Overcome Prefertilization Barriers of Distant Hybridization in Loquat
https://journals.ashs.org/hortsci/view/journals/hortsci/55/3/article-p287.xml (https://journals.ashs.org/hortsci/view/journals/hortsci/55/3/article-p287.xml)

With these papers in mind, I've been looking at the different genera which are closely related to Eriobotrya. The most closely related genera according to several papers are Rhaphiolepis, Heteromeles, Photinia and Stranvaesia. I am currently collecting different promising species and varieties. So far I have:

Eriobotrya deflexa (Small seedling)
Eriobotrya japonica (5x 8yo seedling trees)
Eriobotrya japonica 'Tanaka'
Heteromeles arbutifolia
Photinia niitakayamensis
Photinia prionophylla
Photinia serratifolia 'Crunchy'
Photinia villosa var. maximowicziana
Photinia x dummeri 'Winchester'
Photinia x fraseri 'Faros Red' & 'Chico'
Rhaphiolepis indica 'Spring Time'
Rhaphiolepis umbellata
xRhaphiobotrya 'Coppertone'

So far only R. indica and R. umbellata have flowered. I have saved pollen from both of them and will attempt to pollinate E. japonica flowers if my seedling trees or E. japonica "Tanaka" flower this year. I am also in contact with two people that have Eriobotrya species besides E. japonica/deflexa. I've asked them for seeds/plant material and will hopefully hear from them if their trees flower/fruit this year.

PS: A curiosity I came across ;)

Great post Patanax

Do you think they could cross with a apple maybe even a hawthorn
(since pear pyrus and sorbus mountain ash (rowan berry) cross making a shipova maybe it is possible)

I am wanting loquat pollen as they are flowering now
I would pay Cash ?

I know they saw copper tone is a ornamental most likely but what do those berries taste like I wonder
I do not listen to what is edible online (as loquats are listed in peoples opinions as not edible online)

I will be going to Raleigh North Carolina in a week anyone know of a tree nearby let me know.

I will have to look into the species you mentioned
So quickly reading a few seconds I see Photinia is close with the Aronia berry

When I have more time I will look into it I have the whole winter (that is If I source pollen)
but loquat with aronia that would be interesting wonder if Firethorn down south would cross.

If I did try I would dillute pollen with bread flour to extend it as only one pollen grain needs to make a seed and try different stuff.

"Novak" is said to flower multiple times so in the spring as well. Unfortunately the scions were sent to me so late, practically in the fall, so I didn't get a graft to take on my loquat seedling. Which then also killed the entire plant because I topped it for the graft.

I grafted a bud to an outdoor apple tree as an experiment which looks like it healed. We'll see in the spring if it grows at all.

I've seen atleast one of the two for sale on online European nurseries, don't remember which as I live in the US and didn't make a note of it. There is one youtube gardener based in the UK who has a Rose Anne which is also said to flower multiple times, maybe you can ask him where he got it "Joes Tropicals" he has a video of it blooming in middle of August (summer)

Are there sources for Novak and Shambala in Europe?

I meanwhile have a Rose-Anne and a Piera. Piera bloomed in July and is no longer mature before winter. If it always flowers like this, I assume it's an early-flowering variety rather than a late-flowering one.

I'm still looking for E.prinoides, but no chance. Even google only lists a few hits. All in Asia.

I managed to visit Eriobotrya hookeriana, and grow some seedlings. Attempted few grafts from the parent tree, but not expecting them to take as the grafts were not performed in optimal conditions.
