text: a large American Chestnut in Ohio was discovered that was well resistant to the blight among a grove of dying and dead trees; some budwood was sent to a Dr. Robert Dunston in North Carolina who bred the stock with some cultivars of Chinese Chestnut and backcrossed some with parent American and Chinese Chestnuts and came up with the Dunston Hybrid Chestnuts that probably are about 2/3rd American on average, that are more upright and straight like the American, but more spreading with bigger nuts like the Chinese.)
