Abstract:
On the basis of D² analysis, forty two genotypes of soybean were divided into seven clusters with varying degrees of divergence. D² analysis showed that the genotypes were very diverse, with D² values ranging from 14.11 to 57.98. Cluster VII and cluster V had the greatest inter-cluster distance (57.98). Cluster III and cluster I had the smallest inter-cluster distance (14.11). The maximum intra cluster distance was found in Cluster VII (13.96). However, just one genotype was present in clusters III, V, VI. The large range of D² values confirms the genotypes significant genetic diversity. The cluster V showed least cluster mean for days to maturity i.e. genotypes in cluster V were earlier than that of other clusters. Cluster VI had the highest cluster mean for plant height. Cluster VII genotypes had the highest cluster mean for number of pods per plant, followed by cluster VI. Cluster VII genotypes reported highest cluster mean for seed yield per plant. Seed yield per plant (36.82%) was the trait that contributed the most to divergence among the 10 variables under investigation, followed by 100 seed weight (33.33%), plant height (10.69%), protein content (8.13%), and oil content (5.57%).
