Conventional wisdom says that the Ohio River is more or less the ‘dividing line’ between the 60 and 90-chromosome races. I’m well south of the Ohio… more or less right on the KY/TN line… so, all the natives in this area should be 60s… I’ve not grafted any male 90-chromosome cultivars, but all my 90-C females have seeds… some years fully seeded, some years less than others.
I’m through worrying about it. They all taste good… and I can’t say that I can discern any significant difference in flavor between D.v. cultivars… though some, like Keener (alleged by some to be a hybrid, but I think not) have more ‘fiber’ in them than others.
