Ilya11, your post about Okinawan citrus is interesting.  I lived on Okinawa for two years, and don't remember seeing a citrus tree of any type.

Me too Millet. I did a lot of exploring around the island and can not recall seeing one citrus there. Perhaps my mind was on other things.

Radoslav,

In recent publication on citrus hybrid origin based  on DNA markers it was concluded that:

"Thus, kabuchi was inferred to be an offspring of kunenbo-A as seed parent and an unidentified variety, and
keraji was inferred to be an offspring of kabuchi and kunenbo-A, but their combination was indeterminate.
This inferred parentage suggests that keraji is a backcrossed offspring of kunenbo-A."


https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0166969


Hello,

I found another paper which  assumes that Keraji can be a cross of Kunenbo and Kikaimikan (Kabuchi). https://ir.kagoshima-u.ac.jp/?action=pages_view_main&active_action=repository_view_main_item_detail&item_id=2762&item_no=1&page_id=13&block_id=21
In another paper  this author states, that only morphologicall difference between Keraji and Kabuchi is smell of the fruit.

Radoslav,
That is exactly what is claimed in DNA paper: Kabuchi is a hybrid between KunenboA and and unknown citrus variety with Keraji being its backcross to Kunenbo (KunenboA X Kabuchi).
For morphological differences- I just sent you by email two original  papers with  descriptions made by T.Tanaka
Best regards,
                       Ilya

Diferences between  citrus oto, citrus keraji var. kabuchi, citrus tarogayo and citrus tarogayo Unju in peel thicknes, shape of fruit and shape of seed.
