Our primary source of blight resistance is Chinese chestnut, because that was identified as the most resistant species by the USDA in the 1930s.
No resistance was known in American chestnut
until the 1980s. We also have a few crosses with Japanese and European chestnut.
C. henryi and C. sequinii also may have individuals
with high resistance, based on recent observations
in China.
