The present investigation consists of 20 genotypes of Greengram including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant breeding, SHUATS, Prayagraj during Kharif 2021 following RBD with three replications. The data were recorded on 13 characters to study the amount of genetic variability, Genetic Advance, Genetic advance as percent mean in the greengram genotypes. Based on the mean performance genotype MODAL-L532 followed TOR-2 and SANGU-1972 were identified as best genotypes for seed yield per plant. High significant variation was obtained for all characters studies. High heritability estimates were observed for Number of primary branches, Seed yield, harvest index followed by number of pods per plant, number of secondary branches, biological yield, number of seeds per plant, number of seeds per pod,100 seed weight, days to 50% flowering, days to maturity, days to 50% pod setting, and plant height. High values for heritability indicates that it may be due to higher contribution of genotypic components. High genetic advance as percent of mean was recorded high for seed yield, harvest index, biological yield, number of pods per plant, number of primary branches, number of seeds per plant, number of secondary branches, number of seeds per pod, hundred seed weight, plant height, days to 50% flowering, days to 50% pod setting, days to maturity. Metroglyph analysis shows, analysis of variance indicated that significant variations among the 20 lines for thirteen characters. The scatter diagram revealed that three complexes couldbe distinguished on the basis of morphological variation. Maximum number of genotypes falls in cluster I (10) and II (9) followed by cluster III (1). The germplasm lines, OLTS-B2, MODAL-L532, S/9-1179, SLTS-B2, recorded high index score and fell into different clusters can be crossed to have maximum variability of good combination of characters. Thus, the use of these genotypes in future breeding programme is suggested.
