Most named varieties of cultivated American persimmons are the 90 chromosome race.  Ennis Seedless is thought to be a 60 chromosome type.  I haven't seen any proven 60 chromosome types, but the are said to look quite similar, though leaves may be smaller and thinner and have no pubescence on them, and the fruit is likely smaller.  Certainly, the Ennis I have, assuming it really is a 60 chromosome type, is like that.

 Be sure the understock is 90 C virginiana as 60 C virginiana keep their leaves well after the 90 chromosome. I can supply seed. These trees should harden off early.

 Jerry, Lon, or anyone else,
Is there a simple way to determine if you have 60 or 90 chromosome races?
Seems like Don Compton intimated that the Ohio River was a 'dividing line', of sorts, between the 60s & 90s, but I may have misunderstood.
I usually grow my own seedlings from seed collected from a tree just up the street from my office, which I've designated '816' (the street no.); I suspect that it's probably Early Golden or Meader, but until my own graft of it and EG & M fruit out in my orchard so that I can compare them in close proximity, I can't be sure that that is the case.  
I presume that if it is Early Golden or Meader, it's a 90?
