Analysis of genetic diversity in sesame (Sesamum indicum L.) germplasm for yield and its attributing traits

The  genetic diversity of 50 sesame genotypes was studied by Mahalanobis D2 statistics. By using Tocher’s method, were grouped into nine clusters based on 10 economically important traits viz., days to flowering, 50% maturity, plant height, the number primary branches, secondary capsules per plant, seeds capsules, thousand seed weight and single yield. largest intercluster distance among found between I VIII, indicated that they significantly more diverse IV VI showed lowest indicating under these are closely related. cluster with highest mean in VIII for capsule yield V height VII weight. Taking account a trait, could be selected as parents hybridization program create superior cross combinations. Keywords : Genetic diversity, Cluster, Germplasm, Sesame, analysis
