Re: [nafex] Blight resistant American Chestnuts

That's interesting. They are, in a sense, competing with the American Chestnut Foundation

http://www.acf.org/mission_history.php

The ACF also has some blight-resistant trees, and expect to have resistant trees available for planting in about 5 years. They got there by cross-breeding with Chinese chestnuts, but have been re-crossing and re-crossing with American chestnuts, while testing to retain the small number of genes that is responsible for resistence. They are currently working with trees that are 15/16th American.
