Yates is one of a number of cultivars of American persimmon that appear to fruit parthenocarpically. I say "appear" because even without a known nearby male tree, it's hard to be sure that blossoms are not being pollinated by wild persimmons in nearby forest or by undetected staminate flowers that sometimes appear on female trees of some varieties. Bagging the blossoms would clarify this issue, but even without that, observations I have made suggest that Yates will fruit without pollination. The Yates fruit grown without known pollen sources seldom had more than one or two seeds; this increased to six or more when a male tree was introduced. Also some cultivars in the same location would not fruit at all without a male tree despite heavy blossoming.

This is not to say that Yates should be grown without a resident male tree. Pollination will increase the size of the fruit and the yield of the tree. So it depends what you want. But the wild N.C. seedlings probably will be of the 60 chromosome race and will not provide genetically compatible pollen for the 90 chromosome Yates. If you decide to provide pollen for your Yates, you'd probably be best off adding a grafted 90 chromosome male or a Szukis persimmon, which will flower much sooner than would a male 90 chromosome seedling.

I would not find it difficult to divide all the American persimmon trees that I've seen into two groups: those with smaller, light green leaves and those with larger, somewhat glossy leaves. The former are typical of wild trees I've seen growing in southern and eastern states and the latter of named varieties and seedlings of those varieties, mostly with origins in the midwest. So it's tempting to assume that these groups correspond to the two different races of persimmons, and while that probably is mostly accurate, I wouldn't necessarily jump to that conclusion.
