ABSTRACT

Blackgram (Vigna mungo L. Hepper) is an important pulse crop, which is widely cultivated and consumed in India.  Utilization of divergent parents in hybridization results in promising recombinants. Divergence analysis among fifty genotypes for pod characteristics was carried out using Mahalanobis D2 statistics. The genotypes were grouped into 10 clusters. The contribution of number of pods per plant was the maximum (25.71%) followed by pod length (21.63%). The maximum intercluster distance was observed between cluster I and X (D2 = 325.96). The maximum intracluster distance was reported in cluster I (D2 = 8.11). Based on cluster mean and divergence, it was concluded that the hybridization between genotypes in cluster I (P 9, P 133 and P 133/3) and X (P 133/83) could produce desirable recombinants for grain yield.
