Urdbean is the important pulse crops grown throughout India. It is consumed in the form of ‘dal’ (whole or split, husked and un-husked) or perched. It is used as nutritive fodder specially for milk animals also as green manuring crop. This study aims for estimation of genetic variability in local grown genotypes of urdbean. Its measures allelic richness, expected heterozygosity and percent polymorphic loci. Present investigation studied 50 local genotypes of urdbean evaluated in randomized block design with two replications in kharif-2020 at Botany Section Farm, College of Agriculture, Dhule (MS). All 50 lines were evaluated for different morphological and agronomical traits. Result showed high diversity for most of traits under observations. Combined analysis of variance revealed that mean sum of square due to genotypes for all characters were highly significant and indicate presence of ample variability among genotype. The D2 values between all possible pairs of fifty genotypes studied for seed yield per plant ranged from 61.69 (LCU-32, LCU-42) to 3994.94 (LCU-4, LCU-25). The significant differences due to genotypes with high range in D2 value clearly indicated the presence of adequate diversity among the genotypes studied. Among yield contributing components, the number of seeds per pod (41.63%) contributed maximum for divergence, followed by pod length (28.31%). However, the contribution of protein content (12.73%), seed shattering (7.76%), plant height (2.94%), seed yield per plant (2.29%) and 100 seed weight (1.71%) were moderate. So, this trait suggested important indices for selection of superior genotypes of Urdbean in breeding programs.
