Abstract: The present investigation was carried out with 36 genotypes of mungbean in summer 2018 at Bihar Agricultural University, Sabour, Bhagalpur, Bihar, India to assess morphological diversity using D2 statistics analysis.The analysis of variance revealed highly significant differences among the genotypes for all the traits studied. Thirty six mungbean genotypes (collected from different parts of India) including four checks were analyzed for seed yield and its components by estimating genetic variability. Analysis of variance showed highly significant differences among the genotypes for all the traits under study. In the current study, high heritability coupled with high genetic advance as percent of mean were exhibited by the characters like harvest index followed by seed yield per plant, number of pods per plant, number of clusters per plant, biological yield per plant, number of primary branches, number of secondary branches, number of pods per cluster, plant height and 100 seed weight which depicts that these characters are governed by additive gene action and could go for selection program without progeny testing. High heritability estimates were recorded for the traits viz., 100-seed weight, followed by grain yield per plant, biological yield per plant, number of pods per plant, number of filled pods per plant, number of secondary branches per plant and plant height. In general phenotypic coefficients of variation were observed to be greater than their corresponding genotypic coefficients of variation. Hence these traits could be used by breeders for the improvement of seed yield resulting in the unfolding of high yielding varieties of mungbean.
