Abstract: Genetic diversity analysis is a powerful tool in quantifying the degree of divergence between biological populations and to assess the relative contribution of different components of total divergence. The aim of present investigation is to study the genetic divergence and clustering pattern of 40 genotypes of Mungbean [Vigna radiata (L. ) Wilczek] for selection of suitable parents that can be utilized in hybridization programme and to study the genetic parameters attributing to yield. The crosses of genotypes from cluster II, i. e. PLM-818, PLM-829, PLM-841, PLM-884, PLM-891 with those of genotypes belonging to cluster V i. e. EC-206971, EC-206979, EC-206975, EC-206973, IC-08592-3, IC-10492, PLM-0003, PLM-0021, PLM-0032, IC-10497 has the highest inter cluster distance and might produce high level heterotic response of segregating population with regard to yield. High heritability estimates coupled with high genetic advance was observed for plant height and number of pods per plant resembling the action of additive genes in controlling these particular characters and selection would be rewarding for yield improvement.
