Mung bean (Vigna radiata L.) germplasm comprising 84 genotypes was evaluated at Pulses Research Institute, Faisalabad (Pakistan) during summer 2013 in randomized complete block design with two replications. Variances due to genotypic and phenotypic expressions, heritability along with genetic advance exhibited in percentage of means for yield and its components were deliberated. High genotypic variance and high phenotypic variance for number of pods per plant (15 7.61, 169.14) and days to maturity (54.95, 119.79) were estimated. The Highest heritability was recorded for days to flowering (0.94) while the lowest was found to be associated with plant height (0.46). High heritability along with high genetic advance presented in percentage of mean for number of pods per plant and cluster per plant, depicted the additive gene effects. Correlation studies presented that Seed yield per plant possessed highly significant positive correlation with days to flowering, days to maturity, plant height, number of pods per plant, and number of clusters per plant. Path analysis studies showed that plant height and cluster per plant had maximum positive direct effects on seed yield.
