Sixty four wanggol cultivars were largely classified into ten varietal groups, and six groups out of them forming the group by one variety to high variation in various characteristics whereas the others tended to low. Group Ⅰ and Group Ⅴ contained fifteen (23%) and thirty nine cultivars(61%), respectively Group Ⅱ showed medium or late flowering, but Group Ⅴ revealed early flowering and considerably large variation in various characteristeics. Most of the varietal groups were not associated with their geographical origin. Days to flowering and plant height among the nine characters were the largest contributors to the D²in both intra and inter groups.
