The giant American chestnut tree all but disappeared 70 years ago, killed by a blight that struck at the turn of the last century. [10][11] Chinese chestnut trees have been found to have the highest resistance/immunity to chestnut blight,[12][13][14][15] therefore there are currently programs to revive the American chestnut tree population by cross-breeding the blight-resistant Chinese chestnut with the American chestnut tree, so that the blight-resistant genes from Chinese chestnut may protect and restore the American chestnut population back to its original status as a dominant species in American forests.[12][13][14][15]. Time will tell if the progeny of these best chestnuts exhibit durable blight resistance in different stress environments. American Chestnut trees are vigorous fast-growing trees, with delicious, sweet kernel nuts. The giant American chestnut tree all but disappeared 70 years ago, killed by a blight that struck at the turn of the last century.

This disease was accidentally introduced into North America on imported Asiatic chestnut trees. Each tooth ends in a bristle tip. The tree's huge population was due to a combination of rapid growth and a large annual seed crop in comparison to oaks which do not reliably produce sizable numbers of acorns every year. [40] They believe that by making intercrosses among resistant American chestnuts from many locations, they will continue to improve upon the levels of blight resistance to make an American chestnut that can compete in the forest. It can be distinguished from the American chestnut by its hairy twig tips which are in contrast to the hairless twigs of the American chestnut. Buckeye trees have fans of five leaves while American and horse chestnut leaves are spans of six or seven. This lets the fungus fulfill its normal lifecycle without the death of the tree.

The first step in deciding whether your tree is a possible chestnut is to distinguish it from other trees which can be mistaken for chestnut trees. However, the stump sprouts rarely reach more than 6 m (20 ft) in height before blight infection returns, which therefore, is classified as functionally extinct[21] since the Chestnut Blight only actively kills the above ground portion of the American Chestnut tree, leaving behind the below ground components such as the root systems. American chestnut if your tree has long toothed pendant leaves like this, it may be a member in the chestnut family. The mechanism of resistance of Castanea crenata to Phytophthora cinnamomi may derive from its expression of the Cast_Gnk2-like gene.
