Significant genetic variation was noted among 50 black gram genotypes, providing rich potential for crop improvement.
The analysis grouped genotypes into seven clusters using Mahalanobis D² statistics, with Cluster I containing 30 genotypes.
Intra-cluster distances ranged from 0.00 to 24.11, highlighting notable diversity, particularly in Cluster III with the highest divergence.
Key traits such as plant height and seed yield accounted for about 86.90% of total genetic divergence, guiding breeding strategies.

Analysis reveals significant genetic variability and stratification of black gram genotypes, indicating potential for hybridisation.

Tripathi et al. (2025) studied this question.
