The present study was conducted to assess the genetic variability, correlation coefficient and path coefficient analysis of 50 mungbean genotypes. The observations were recorded on nine quantitative characters viz., time of flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, pod length, number of seeds per pod, 100-seed weight and seed yield per plant. The study was carried out at Pulse Research Station, Junagadh Agricultural University, Junagadh during summer 2022 in a randomized block design with three replications to estimate the extent of genetic variability and association between yield and yield related traits. The high values of GCV and PCV were recorded for seed yield per plant followed by plant height and number of pods per plant. This indicated the presence of wide genetic variation for these characters. High heritability coupled with high genetic advance as per cent of mean was observed for plant height, 100 seed weight and seed yield suggesting the existence of sufficient heritable variation and wider scope for effective selection. Number of pods per plant, number of branches per plant, 100 seed weight and number of seeds per pod showed positive significant phenotypic and genotypic correlation with yield. The result of path coefficient analysis revealed that number of pods per plant exhibited high and positive direct effects on seed yield per plant. While number of branches and plant height exerted low and positive direct effects towards seed yield per plant.
