In this study, we aimed at finding the genetic regularity of grape maturation period. Early-maturing grapevine, “87-1”, was used as the female parent and late-maturing, “9-22”, as the male parent, to create an F1 hybrid population. A total of 149 individual plants and their parents were selected as the mapping population. Sequence-related amplified polymorphism and simple-sequence repeat analyses were performed. We performed a linkage analysis and constructed a molecular genetic map.
