Abstract
Black gram is one of the important sources of easily digestible good quality protein and micronutrients. It fits well in diversity of cropping pattern, used as green manure. Diversity occur in both qualitative and quantitative traits, high genetic diversity builds a sound gene pool gene for future use and serves as breeding material for crop improvement. The present study aims at analyzing the genetic divergence of 120 genotypes along with 3 checks (Rashmi, DU 1 & T9) were evaluated in augmented design at University of Agricultural Sciences, Bengaluru. K mean analysis shows that high genetic diversity for yield and its attributes. After eliminating the unknown sources of variation, the accessions are grouped into 5 clusters and the range of inter-cluster distance is between 8.128 and 28.432. Cluster 1 accounts for maximum number of accessions (27) followed by cluster 2, which include 26. The clusters which accounts for least number of accessions are 5th cluster i.e., 19. The maximum inter-cluster distance is 28.432, which is observed between cluster 2 & cluster 3 and minimum inter-cluster distance is seen between cluster 4 & cluster 5 which is 8.124. Therefore, any selection made between cluster 2, cluster 3 and cluster 4, cluster 5 rewards maximum benefits for yield improvements
