Thirty blackgram genotypes evaluated for genetic divergence under organic fertilizer management for 17 parameters including yield, yield component and water use efficiency traits were grouped into seven clusters by Mahalanobis ’D2 analysis. Hundred seed weight was recorded as the major contributor towards genetic divergence. The crosses PU-31 × KU-14-01, KU-12-56 × LBG-752 and KU-12-56 × KU-14-01 were identified for successful utilization in hybridization programmes to get desirable transgressive segregants for yield and water use efficiency.
