Citrus General Discussion / Re: Who here has a citrus cross breeding project?
« on: December 10, 2023, 11:17:51 AM »
Sylvain, are the hybrids with the Australians also early flowering?

Malcolm Smith told me that the precocious trait was diluted very quickly in their breeding program. But that was with hybrids of common citrus.

Thank you, your help is really valuable!

Btw do you know what variety is behind "early clementine" at Lenzi? I noticed the red dots on your picture, as a marker for Lenzi.

"early Clementine" is supposed to have a ripening period from November to January (according to Lenzi) then it could be Nules.

I am interested in a clementine that produces zygotic seeds when cross-pollinated. Are there varieties that reliably produce zygotic seeds?

If a clementine is crossed pollinated then the fruit is seedy.

Is this the case with every type of clementine? I am specifically looking for varieties that produce seeds

I saw the name Tom McClendon on Don's blog. Tom McClendon posts on Facebook and has started a new citrus blog himself.

I am searching for an SP Urban.


Does anyone in Europe have budwood or even better a plant to share?


Thank you very much!

Good job Ilya, your plants grow very fast. Mine is still small. far away from its first flower.

Well done! Let`s hope for a short juvenility. 
Is Valentine more effective than Chandler to diminish the acidity in its progenity?

Cold Hardy Citrus / Re: The eremo- hybrids, which ones are worth it?
« on: October 10, 2023, 08:44:44 AM »
what about this one?

https://bluewood.yo.fr/produit/eremomandarine-hybride-satsuma-eremocitrus/

in the picture there is a label glauca x Shekwasha, so nothing special. But the description says Hybrid of satsuma-eremocitrus.
The label that comes with the plant says Eremosatsuma.

Who can help?

Hi Mikkel,
An interesting observation. How old was citrumelo rootstock?

Hi Ilya,

it is a probably 3 years old rootstock. I assume it is polyploid. It grows very fast, has leathery leaves and serrated leaf margins. I think it is a Swingle seedling, but i am not sure.
It is 1,50 m high and has already formed a crown on its own, which is probably very helpful. So it may be a simple coincidence, but I want to test it further.

Hello Ilya, I grafted a mature IchangStar 60 budwood into the crown of a 3 year old Citrumelo seedling, in spring the IchangStar 60 budwood started flowering and so did the Citrumelo shortly afterwards. This may be a coincidence, but I repeat this experiment, let`s see what happens next spring. I come to it because you write about the 100 5starXDunstan seedlings.... Could be a long time to wait for these to flower....

Walt, my "Holy Grail" would be a zygotic Conestoga series tree.
In my experience, pollination by Ichang Papeda often resulted in zygotic seeds. even in otherwise nucellar varieties. (But this is only anecdotal and not confirmed!).

Is it a certain variety? Summer flowering is a rarity in loquats. Only in some varieties this is the case.

One green world in Portland has some really great maypop varieties. I got a bluePop from them last year, it flowered a bunch but didn't set fruit.
https://onegreenworld.com/product-category/vines/passiflora/

Judged by the flower, BluePop is probably a hybrid of incarnata and caerulea. These are often sterile and rarely form fruits, and when they do, they are often hollow.
In any case, you need a second variety for pollination to have a chance of fruit.

I understand the Australians have one as well, but it's noted to struggle. Not so much that it dies, but it's not exactly happy about it, either.

Microcitrus australasica x Poncirus hybrids also have been done in Florida by Ethan Nielsen. @ethane

Cold Hardy Citrus / Re: US-802 citrumelo
« on: August 10, 2023, 05:29:44 PM »
looking at these pictures I had the idea it might be a polyploid.
https://idtools.org/citrus_id/index.cfm?packageID=1179&entityID=8884
I have a polyploid citrumelo chance seedling that grows like crazy. Even in my climate.

Anyway, if 802 is from Siamese Sweet, it sounds interesting for breeding. But I rather suspect that it is a standard Siamese offspring (but that's just an idea I had when I read about it on the internet).

Probably hard to get? or can you order it from UCR?

Also this is a desire of mine: large, sweet and glochidless opuntia

maybe this one is interesting for breeding

on EFN there was an O.stricta type with similar traites (now it has disappeared)

Do they bloom as quickly in Paris as in the south?
I have never had a flowering plant. Neither as a seedling nor as a graft.
