Hi @PaulinKansas6b, hope to hear from your experience with russian jujus in kansas! Unfortunately we only got to try 2 out of the 6 you posted, and could only recall russian#2(supposedly the same as kitaiski60) . Also couldn’t recall the other russian cultivar that we grew(possibly 29-16 toc or sovietski), but the fruits were so coarse we didn’t even bother documenting it.
i agree. It was either a chinese cultivar that the soviets liked and didn’t change the name. Or that it was actually bred by the russians which the chinese liked and re-named. Jujus can be bred readily from seed, and highly unlikely to have the same exact genetics as either of its parents
incidentally, “Ta” is large in mandarin, and “Tsao” is common name for jujube(of any variety) in chinese.
btw, russian #2 bears similar fruits to sugar cane in las vegas’ conditions. It likely bears better quality fruits in areas with summers cooler than 105F.
we have a photo of russian#2 here
and photos of other soviet bloc jujus(trademarked by onegreenworld nursery) on this link
the trademarked jujus i obtained from burntridgenursery and one green world(which involved lots of confusion and uncertainty, even up to this day), some of them had to order twice just to check for differences, since labeling errors occur all the time.
while the kitaiski and my other unrecalled russian juju was from R. Meyer.
btw, @castanea should be included in the ‘subpoena’ . Not sure if castanea has grown any in that list, but likely may have come across some of them-- being based in california. Actually think castanea has tried as many, if not more, cultivars as i have.
