Kābuchi  (C. keraji hort. ex Tanaka var. kabuchii hort. ex Tanaka) カーブチ (かーぶちー)
is common citrus.

In the same DNA marker  paper it is shown that Kabuchi and Unzoki are hybrids of Kunenbo-A  and unknown citrus with cytoplasm coming from sweet orange, while Keraji is a back cross of Kabuchi to Kunenbo-A

In one DNA study I read, that kabuchi is kunenbo x citrus  yatsushiro in another kunenbo x something like citrus depressa.
Kabuchi is chance seedling from Okinawa.

My apologies, it is indeed spelled kabuchi.

Kabuchi is chance seedling from Okinawa.
That would be interesting, so it appears keraji is a triple backcross of kunenbo with some other original citrus. Probably some sour citrus I am guessing, maybe Yuzu.

Kunenbo appears to be some sort of mandarin x tangelo hybrid, or something like it, analogous to the type of citrus known as a tangor (Temple orange and Page mandarin could also fall into this category). What I mean is that kunenbo probably has a buntan (pomelo) ancestor going back two or three generations. That would explain its fragrance. Whether it also may have some other cold hardy species in its ancestry (like Yuzu) I'm not sure. I will point out that it doesn't necessarily have to have been descended from a cold hardy species to develop a fairly high degree of cold tolerance over several generations. The central coastal region of Japan can get quite cold some Winters, every 25 years or so. That could have killed off the less hardy citrus. From there it would be natural selection as the citrus gradually started making its way up North, over successive generations. This would also leave me inclined to think that kunenbo is probably at least in substantial part zygotic, although I don't have any information on that.

I know Sudachi is pretty cold hardy (maybe not quite as hardy as Yuzu). I read on another site someone was managing to grow it outside near Portland, OR.


Yes, My Sudachi and Yuzu easily survived 8F (-13.3C) in January 2017 in Vancouver Wa., just across the Columbia river from Portland Or., with only minor small twig damage and about 20% defoliation on each.  The Sudachi appeared to have a higher percentage of small twig damage than the Yuzu.  On the other hand, the Yuzu is a much larger tree, and size does matter.
