A few super-hardy C. ichangensis hybrid seedlings
« on: January 19, 2019, 02:06:41 AM »

Citrus ichangensis x Poncirus trifoliata (N1tri) seedling



kumquat x C. ichangensis (Ichangquat) seedling



some Yuzu (C. junos) seedlings
Yuzu has a really close genetic relationship with C. ichangensis, it may even be descended from it (possibly as a result of genetric introgression from another C. reticula-like citrus species). Some see Yuzu as a C. ichangensis hybrid (constituting an Ichandarin), although it's certainly not a direct hybrid. Yuzu isn't quite as cold hardy as C. ichangensis, maybe but it is a more vigorous and fast grower and can easily recover from damage. Also the leaves of C. ichangensis smell nothing like Yuzu, although they do share a same distict "deepness". Otherwise the smell of C. ichangensis leaves are very mild (maybe a bit like Kaffir lime leaf) and a bit lemony. The leaves of Yuzu are practically like petitgrain (strong, green, harsh, petitgrain is made from the leaves of bergamot citrus). The fruits of Yuzu are very fragrant though (like a mixture of sour orange, Satsuma mandarin, lemon, and maybe a hint of grapefruit sweetness, and also it is a pungently deep spicy smell).

I wouldn`t say N1tri is "super hardy". e.g. N1tri is not suited for growing in open ground in northern Germany. US852 and Citrumelo are hardier here.
I don`t know how hardy it can be in numbers. I suppose prolonged cold spells are the bigger problem.
Your seedling might be a zygotic seedling. When grown up it should have petiole wings.

It would be more interesting if it is, actually.
Might get something interesting.

What do you think the chances of Ichangquat seeds turning out to be zygotic are?

(none of them so far have turned out to be polyembryonic)

Ichanquat 6-7-2 is 100% zygotic, moreover approximately one third of its seeds contain embryos with green cotyledons like those of kumquat.
Best regards,

They grow so fast!

these came from seeds from Ilya
