Genetic variability and character association were studied in forty mungbean genotypes for different quantitative characters during rabi, 2012. Highest GCV and PCV were observed for number of branches per plant, pods per plant, biological yield per plant and harvest index, respectively. High estimates of genetic advance as percent of mean were observed for 100 seed weight and harvest index. High heritability coupled with high genetic advance as per cent of mean was observed for plant height,

Hence, direct selection may be exercised for improvement of these traits. Eestimates of correlations revealed that seed yield had positive and significant correlation with number of pods per plant, clusters per plant, number of pods per cluster and biological yield per plant. All these traits had significant and positive association with branches per plant might play a vital role in indirect selection for yield.
