Very interesting publication. Especially since the relation between the citrus from the ryukyu islands are explained in detail.
I however wonder if the citrus were just a random found or if there are more trees in the wild.
In 2019 I was also on the Ryukyu Islands and remember that I saw a wild citrus trees on one of the smaller islands in the bushes. I however could not see fruits on the tree and due to toxic spiders and snakes and did not walk trough the brush. I always thought this might me a wild Shikuwasa or Tachibana. Now I wonder even more what species/hybrid that was.

My guess is that none of these varieties are not cultivated to any extent. I lived on the Ryukyu islands (Okinawa) for two years and never seen a citrus tree of any kind.

It’s pretty surprising, because Shukuwasa is extensively grown in the norther part of the main island (Okinawa). The fruits are sold everywhere on the island in different degrees of maturity. I just wonder how common it is to find the named C. ryukyuensis. Apparently C. ryukyuensis is monoembrionic, while Shikuwasa is polyembrionic and it was more by chance that it was found.

Stefferngot, that is possible because the vast majority of the population lives in the central and south portion of Okinawa

Indeed very interesting articles.
Would be nice to have the contact to the local farmer Hiroshi Kobashigawa. He grows Shikuwasa and has apparently some citrus ryukyuensis growing on his farm.

Yeah I also found that article. But could be nice to have an email adress or to know where his farm in Ogimi is.

"Citrus Genetic Resources Grown on the Ryukyu Islands, Japan" Not up to date, but has images of some of the other Okinawan types mentioned as the yukunibu group. core.ac.uk/download/pdf/144573096.

One of the articles I saw mentioned that some of the Okinawa Citrus sampled came from a private collection in Okinawa. I wonder if any members have ever heard of Citrus collectors or hobbyists in Japan ??

Then C.inchangensis cannot be the seed parent of yuzu.
