Two hybrid seedlings grew from one seed of the Valentine pomelo pollinated with PT. Information about this possibility has been found in the literature.

Looks quite interesting with first valentine and then
trifoliat leaves.
Will you make an early freeze test ?
Leave taste also would be interesting.
Good success

That's great Boris, good luck with them!

I read about this a while back. It seems that polyembryony isn't just caused by somatic embryos, but that two identical zygotic plants can also emerge. I don't remember where the article was or the name, but I remember reading it, and it confirmed what I saw with Nagami and the Limequat Eutis. I've seen two plants sprout from one seed, and they're both monoembryonic (although the Limequat can produce some apomictic embryos, but Nagami can't).

It was described in the case of triploid seedlings.
There is also an article pointing to about 30% of triploids among orangeXPT crosses.

Thanks for the wishes!
When they grow up a bit, of course I will test them. It 's too early to taste it 😅
