Hi Lucky,

That well describes my assessment also. But if I have the opportunity I'll 
have it's DNA ran also. 

Several years ago I had this idea that maybe D. v X k hybrids might be say 
90% of the seed parent and would take several crosses of the those 90% progeny 
to reach maybe 80/20 then crossed again before something like 50/50 hybrids 
would be reached. But this idea was received coolley by people more educated than 

It was written in Russian at the Yalta station where Rosseyanka was bred, it 
was achieved by "Many years double Mentor."  When I asked what that meant they 
didn't know and the author had died years before. Also it was recorded as 
Rosseyanka 18 giving me the idea there were several hybrids were achieved but #18 
was the best. I've not been able to confirm that either.   

One method used to hybridize difficult species is doubling the chromosomes 
using colchicine. If increasing the sets of chromosome to 4 makes it easier, why 
don't persimmon hybridize very easily as they have 3 sets of chromosomes?  Go
