Varietal Classification by Multivariate Analysis in Sesame

1. Seventy seven sesame cultivars were bargely classified into six varietal groups, but those were aggregated into two varietal groups except four varieties forming each varietal group solely. Group I also can be classified into some sub-groups and eighteen clutivars fail to form varietal group. 2. Group I and group II contained fifty four (70%) and nineteen cultivars (25%), respectively. Most varieties in Group I showed medium or late flowering and considerably large variation in other agronomic characteristics but varieties in group II revealed early flowering, and relatively narrow variability and inferiorty in vigorosity and yield components. 3. Most of the varietal groups were not associated with their geographical origin. 4. Days to flowering and plant height among the nine characters were the largest contirbutors to the D² in both intra-and inter-groups.
