WebA biological control imported from Europe in 1972 allows us to keep American chestnut trees alive for breeding, and may be improved for better spread in the forest (1). Breeding projects are underway to combine the nut quality and timber form of American chestnuts with blight resistance of Asian chestnuts to produce trees for orchards and forests.
Webchestnut plants (5). Similarly, imported Asian chestnut plants may have been the source of the epidemic of chestnut blight in Europe. This hypothesis is suggested by the fact that, in Spain, chestnut blight was first noted in 1947 on C. crenata (22) in a stand of apparently healthy C. sativa.
