An experiment was conducted with a set of twenty barley genotypes in alpha lattice design with objective to screen out high iron content genotype with high yield. From the study of genetic parameters, days to booting, flag leaf area, spike length, and thousand grain weight had better genotypic variability, better broad sense heritability along with better genetic advance. Soluwa (309.395ppm), Bonus (235.035ppm) and 14-SB-NAK-MR#17 (154.065 ppm) had high iron content and the character f iron content was found to be 100% heritable with no environment effects. Similarly, SBYT2-13#1519 (3120 kg/ha), SBYT2-13# 108 (2780 kg/ha), 1STGSBYT#122 (2410 kg/ha) were found to be high yielding genotypes. As the genotype with high and high iron content were screened out and this may be further use in development yield of high yielding varieties along with high iron content which can address issues of both food scarcity and nutrition demand.
