Micronutrient deficiency is reported in more than 2 billion people and is more serious problem in developing countries. Food fortification, agronomic fortification and biofortification are the possible solutions. Biofortification is most feasible and sustainable for resource poor. It requires multilocation germplasm evaluation, study of genotype and environment interaction (GEI) and use of conventional and molecular tools for development of Fe and Zn rich varieties. In the present study, 96 lentil genotypes were evaluated at three locations to determine the extent of variability and to study GEI for grain Fe and Zn concentration.Large variation was recorded for grain Fe and Zn concentration. Using Eberhart and Russel model for grain Fe concentration, genotypes P 2124, P 2126 and P 2127 having unit regression coefficient (bi=1) and non-significant deviation from regression (S2 di = 0) were found to be stable. Similarly for grain Zn concentration genotypes NDL 11-1 and L 4648 were found to be stable. The stable genotypes identified in the present study can be to develop bio fortified lentils.
