ABSTRACT
Multivariate analysis of divergence among 50 genotypes of blackgram for eight characters revealed considerable genetic diversity among genotypes and led to their grouping into seven clusters. The cluster I was the largest containing 24 genotypes followed by cluster II with 20 genotypes. Cluster VI had two genotypes and rest four clusters (III, IV, V and VII) had one genotype each. Pods per plant contributed maximum towards divergence followed by days to 50% flowering and seed yield per plant. The genotypes included in the diverse clusters can be used as promising parents in intermating for obtaining high heterotic response and better segregants.
