I may be able to get some seed of E. hookeriana - but not any time soon, probably next year. I'll also keep an eye out for any loquats growing at their Southern limit here.

Hello JSea,
that's great to hear :D
Are you visiting China or the Himalaya region or do you know a botanical garden in your area that has them?
Definitely keep us updated on the progress. If you're able to aquire seeds, I'd love to buy some from you :)

Is there a nursery in Spain which is offering Piera?

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.

It's from a botanic garden quite a few hours away. I'm also close to the Southern limit of loquat growth here so will also keep an eye out for very tough trees dealing with hard frosts.

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

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

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

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 ;)

Maybe he is in the southern hemisphere.

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.

I've heard you can graft loquat on firethorn. I'm gonna try it eventually. There's a wild firethorn bush down the street from me if there's any interest in the seeds. Berries on it now. Have a few growing from last year's seeds for my own projects. Be awesome to have a severely dwarfed but yet highly productive quality fruiting loquat.
Trying to grow it all!

Thats what Quince is for too , if that one grows easily at your location as well.
