The big take away for me is that OzC is genetically distinct.
It is also higher on the nutrition scale.
OzC would seem to have big potential especially since in produces fast in poor soil.
The more they find out the more interesting it gets.
I just sent a letter to a man in MO to get scions from some ozark chinkapins. He's told me they can be grafted to Chinese chestnuts. I'm gonna try that this spring and thinking about burying the graft union to avoid incompatibility issues with some of them.
