Abstract
We have added 275 AFLP and 24 SSR markers and the 5SrDNA locus to a previously published genetic map based on a hybrid cross between
Castanea mollissima and C.
denata. The SSR markers, 5SrDNA locus, and one isozyme locus also permitted us to correlate the linkage groups in the published genetic map of C.
sativa with those in our C.
Mollissima/C.
dentata map. Correlating the map of European chestnut with that of American and Chinese chestnut will allow greater progress in mapping important physilogical and adaptive traits across species boundaries.
