Matthew, I don't think Chinese-American hybrids are that common in the wild but I know some of them exist. The Dillingham trees may be two of them. Chinknut ( An American Chestnut Chinquapin cross ) is more common.
Yes, the blight is there. These trees have some dead limbs that are almost surely blight caused but the trees are otherwise quite healthy. The American Chestnuts on the Douglas falls trial also show some evidence of the blight but still appear quite healthy. I have found burrs on quite a number of Am Chestnut trees, but sadly all but the Dillingham trees have tiny atrophied nuts. I would have liked to have made it back to Mt. Jefferson to have seen if it had viable nuts. It is a nice well formed tree. I dream of a 100ft chestnut with viable nuts!!
