I was thinking it may be a good idea to add in more information about the American Chestnut Foundation's work, where some other hybrids are planted (like on the Flight 93 National Memorial site), and maybe discuss more about how the fungus affects other hardwood species.

I was reading about the Chestnut blight, and noticed that this page and the American Chestnut page seem to have different sets of information regarding the Chestnut blight. Perhaps these two pages should be merged together, or the American Chestnut page merely point to this page? Dandube 22:55, 2 November 2005 (UTC)

Dunstan / Chestnut Hills Nursery spam[edit]

I have removed[1] the following paragraph of text from the article, where it has been retained essentially unchanged for six years since being added early 2010[2]). Efforts by me to verify the existence of the allegedly totally immune tree allegedly discovered by James Carpenter, "...a member of the Northern Nut Growers Association" have failed. On the nursery's webpage,[3] it claims this Mr. Carpenter failed to infect the tree despite numerous attempt at applying the fungus. (Truly this would be the "unicorn tree" preservationists have been seeking for a century.) I can find no scientific literature regarding this tree, and in response to my inquiries to the nursery, they claim that both Mr. Carpenter and his perfect ancestor tree are now deceased, and have no further information.

Given the apparent commercial conflict of interest in both the purportedly once-existent Mr. Carpenter and the nursery, I am concluding that this is unverifiable spam and striking the passage. I have, at this point, no reason to believe that the nursery's trees are substantially different than various other Chinese hybrid strains capable of achieving moderate heights, as the advertized growth characteristics do not suggest that they have successfully recreated the once-dominant apex canopy tree.--Froglich (talk) 21:23, 22 June 2016 (UTC)

In the years since the chestnut blight, many scientists and botanists have worked to create a resistant hybrid chestnut tree that retains the main characteristics of the American chestnut tree. In the early 1950s, James Carpenter discovered a large living American chestnut in a grove of dead and dying trees in Salem, Ohio that showed no evidence of blight infection. Carpenter sent budwood to Dr. Robert T. Dunstan, a plant breeder in Greensboro, North Carolina. Dunstan grafted the scions onto chestnut rootstock and the trees grew well. He cross-pollinated one with a mixture of 3 Chinese chestnut selections: "Kuling," "Meiling," and "Nanking." The resulting fruit-producing hybrid was named the Dunstan chestnut. The grafted Dunstan hybrids grew to a height of only 25 feet or 7.6 meters, but the seedling Dunstan chestnuts grow 50-60' tall, in many locations around the nation.
