The current work aims to performed and know the fifty-one wheat genotypes and evaluate for drought stress. The analysis of variance (ANOVA) was performed, which shows that all the parameters are significant. Variations in quantitative traits include Peduncle length, Spike length, Plant height, Days to 50% heading, Biological yield, Flag leaf area, Yield per plant, 1000 grains weight, Number of spikelets per spike Harvest Index were recorded. The highest peduncle length, spike length, plant height, days to 50% heading, biological yield, flag leaf area, yield per plant, spikelets per spike, 1000 grain weight, and HI were observed in 10831 (46.33), 10843 (14), 10821 (116.33), 10845 (157), 10826 (18.4), 10874 (58.46), 10854 (2.944gm), 10841(26), 11881 (52) and 10738 (24.571) respectively. Seven molecular markers were used for screening drought-tolerant genotypes. The genotypes 11861, 11860, 10850, 10815, 10819, 11866, and 10825 have amplified a maximum number of drought resistance genes as 7, 7, 7, 6, 6, 6, and 6, respectively.
