I work with similar organization called the American Chestnut Cooperators Foundation who have chosen not to seek blight resistance by crossing with the Asian variety. Our goal is to develop an All American blight resistant tree.
I administer a grove containing approximately 30 all American trees grown from seeds developed by crossing trees exhibiting blight resistance such as the one noted in New Hampshire.
I can very proudly report that I currently have 7 small trees grown from chestnuts produced on the trees in my grove.
Most of my trees exhibit aome blight resistance. I have one producing burrs that so far has no blight. It is 10 years old.

I started my association with ACCF in 1990... saving Chestnut trees is slow work. I have 2 trees that are 17 years old
thanks for bringing me to the thread. See my post above
Bless you for your diligent work. Future generations will thank you too. To work with a living legacy must be very gratifying.
