Abstract: Fifty pigeonpea genotypes were studied for genetic divergence in yield, yield components and quality traits using Mahalanobis D2 statistics and grouped in to three clusters which suggested wider genetic diversity. The maximum inter-cluster distance was observed between cluster-I and cluster-II. The highest intra-cluster distance was exhibited by cluster-III. Cluster-II rendered highest cluster mean values for the characters viz., days to 50 percent flowering (89.13), days to maturity (131.00), number of branches per plant (11.10), number of pods per plant (140.40), harvest index (61.53) and grain yield per plant (55.25). Among all the traits, the contribution of harvest index (43.59%) towards divergence was maximum, followed by number of seeds per pod (16.24%), 100-seed weight (10.69%) and number of branches per plant (8.00%).
