An investigation was carried out to assess the genetic variability among 70 mungbean Recombinant Inbred Lines (RILs) grown in untreated and treated (ZnSO4 and FeSO4) environments and to identify high micronutrient (Zn and Fe) content RILs. Significant variability among the genotypes was observed for all the characters i.e., days to 50 % flowering and maturity, plant height, number of branches, number of pods, number of seeds per pod, 100-seed weight, seed and biological yield per plot, reaction to MYMV, zinc and iron content in seeds except harvest index. High estimates of GCV, heritability and genetic advance in both the environments for number of branches, seed and biological yield, reaction to MYMV, zinc and iron content in seeds suggested that these characters are controlled by additive gene action. Low GCV coupled with low heritability and low genetic advance observed for number of seeds per pod and harvest index indicated presence of non-additive gene action and high GxE interaction. About 43 % of the RILs responded positively to zinc, 71 % to iron and 29 % to both zinc and iron application. RILs having high zinc and iron contents responded less to their application as compared to those having low to moderate zinc and iron content. RIL-1, 11, 34, 37, 59, 61 and 70 were found to have significantly higher zinc content, RIL-1, 3, 7, 34, and 38 had significantly higher iron and RIL-25, 27, 54, 58, 60 and 67 had higher seed yield.
