Probably, I got the immature budwood from Zitrusgaertner labeled as PTxSunki in 2012.
 First flower and one fruit in 2021



No protection and it has never been  damaged.

This spring my PTxSunki has become crazy with flowers






Mine, the mother plant, blooms for the first time at last. But there are hundereds of flowers. Quite tiny yet because of the very low temperatures but I am glad. How was this fruit? Awful?

It is interesting to observe that while US-812 is seed-stable (true to type), later re-crosses between poncirus and citrus sunki are quite variable. This has been exploited to study which genes poncirus uses and which genes citrus has/has not that confer resistance to various pathogens.

https://www.nature.com/articles/s41598-020-77840-2
https://bmcgenomics.biomedcentral.com/articles/10.1186/1471-2164-12-39

Essentially, poncirus is really resistant to CLA/HLB (greening) and phytophthora and citrus sunki is really susceptible to them. So they are frequently hybridized in genetic research to learn which genes are up- and down-regulated in the hybrids that exhibit different levels of resistance or susceptibility. US-812 didn't arise from this source -- it came about due to CTV resistance -- but it remains to be seen if other poncirus/sunki crosses will later be released.

Our professional base ball tea, The Cincinnati reds, referred to them as being in Zinzinnati.  Our city is of German heritage and misspelling it with Z's is supposed to give it a German twist.  With your name of Zitrus.... I though you may be from Cincinnati.

In June I will visit the US and Canada for the first time in my life.

You are brave to visit a third world country like the USA.
