Drought is one of the most environmental stressors, significantly affecting wheat production, particularly in face accelerating climate change. Therefore, developing drought-resistant, high-yielding varieties essential to ensure sustainable production and maintain global food security as world population rapidly grows. This study aimed evaluate genetic variation local imported bread genotypes through simple sequence repeat (SSR) markers assess their combining ability identify top-performing under both normal drought-stress environments. SSR revealed significant diversity among parental genotypes, which were utilized develop 28 F1 crosses utilizing diallel mating design. Field trials well-watered drought-stressed environments demonstrated that drought reduced all measured agronomic traits. The categorized into five clusters based on tolerance, ranging from highly sensitive (group-E) robustly drought-resistant (group-A). variety Sids-12 (P2) was identified an excellent combiner for breeding shorter early-maturing cultivars Line-117 (P3), Line-144 (P4), Line-123 (P5) improving grain yield related traits conditions. P1×P5, P3×P8, P4×P5, P6×P7 possessed superior performance Key traits, including plant height, grains per spike, 1,000-grain weight, spikes plant, displayed strong correlations with yield, providing effective approach indirect selection drought-prone
