Thirty one diverse mungbean (Vigna radiata L. Wilczek) genotypes were evaluated for the estimation of genetic variability, heritability and genetic advance for ten quantitative traits and five physiological traits. The genotypes differed significantly for all the characters studied. Higher genotypic and phenotypic coefficient of variation was observed for Relative Injury Percentage (RI), seed yield per plant and number of pods per cluster. High heritability coupled with high genetic advance was observed for the traits Viz., harvest index, seed yield per plant, relative injury, chlorophyll content, 100 seed weight, specific leaf area, number of pods per cluster, number of clusters per plant, number of pods per plant and plant height indicating the importance of additive gene effects in the expression of these characters. The present findings could be useful for establishing selection criteria for high seed yield in the summer mungbean breeding programmes.
