Abstract
Eighty genotypes of blackgram comprising landraces, varieties and local cultivars collected from different locations were studied for genetic divergence by using D2 statistic. The genotypes were grouped into twelve clusters, cluster I had maximum of 41 genotypes followed by cluster V and VI with 11 genotypes in each. Clusters VIII, XI and XII had one genotype each. The maximum intra cluster distance was found in cluster I. The divergence within the cluster indicates the divergence among the genotypes in the same cluster. Maximum inter-cluster distance was found between cluster III and XI followed by cluster XI and VII, XI and X, XI and III, indicating efficient breeding program can be undertaken to improve productivity and other yield attributes by exploiting heterosis breeding program by selecting superior genotypes in segregating generation. Number of branches, plant height, 100 seed weight and number of clusters per plant had maximum contribution to divergence. Cluster VI had highest mean value for seeds per pod, clusters per plant and pods per plant. Cluster IV recorded highest mean value for seed yield per plant and number of branches per plant. Due importance should be given for these traits for selection of parents for efficient breeding programmes. Lu 18 and VZM 189/65 may serve as potential parents in getting transgressive segregants.
