 ABSTRACT

Divergence analysis among thirty blackgram genotypes for yield, yield contributing and water use efficiency traits was carried out using Mahalanobis D2 statistics. Thirty genotypes were grouped into eight clusters. The contribution of relative water content was the maximum towards genetic divergence followed by SLA at 50 DAS. The maximum intercluster distance was observed between cluster III and VI. The maximum intracluster distance was reported in cluster V. Based on cluster means and divergence, it was concluded that the crosses PU-31 × KU-10-1169, UG-708 × KU-14-01 and WBG-26 × LOP-1070 could be successfully utilized in hybridization programmes to get desirable transgressive segregants for yield and water use efficiency.

Key words: Black gram, D2 analysis, Cluster distance.
