In order to estimate the genetic variability parameters, characters association and path analysis for the various traits, thirty-five genotypes of mungbean were evaluated during Kharif season 2023 at the Research Farm of Agricultural Research Sub-Station, Nagaur (Rajasthan) using a randomized block design (RBD) with three replications. Based on the results, there were significant differences in the mean sum of square resulting from genotypes for each trait studied, indicating that the genotypes were genetically distinct. The PCV values was higher than GCV values for all the characters which reflect the impact of environment on the expression of traits. The estimates of GCV and PCV were higher for number of branches, number of pods per plant and seed yield. Highest heritability estimates were recorded for all the traits. High genetic advance as a percentage of mean along with high heritability was observed for plant height, number of branches, number of pods per plant, 1000 seed weight and seed yield. The correlation of seed yield was positive and significant at phenotypic and genotypic level with characters viz., number of branches, number of pods per plant and number of seeds per pod. Path analysis revealed that at phenotypic level, highest positive direct effect on seed yield was observed for number of pods per plant followed by days to 50% flowering, number of seeds per pod, pod length and number of branches. At genotypic level, highest direct positive effect on seed yield were observed for number of pods per plant followed by days to 50% flowering, number of seeds per pod and plant height.
