Abstract: Achieving the goal of increasing both crop yield and water use efficiency through better precipitation regimes is a major challenge in semi-arid and arid regions. The objective of this study was to assess the performance and agronomic traits and water use efficiency (WUE) of bread wheat genotypes under rainfed and irrigated conditions. This study was conducted in the Research and Application Field of the Faculty of Agriculture at Dicle University in Diyarbak?r, T?rkiye. Nine wheat genotypes were used as the experimental materials. Notably, the first year of the study exhibited decreased values for most traits under rainfed conditions compared with irrigated conditions, a trend that was less pronounced in the second year and varied based on climatic conditions. Noteworthy findings include the high performance of the Din? and Wafia varieties, which displayed significant improvements in grain yield with supplemental irrigation. Heading time, normalized difference vegetation index, leaf area index, plant height, and thousand-kernel weight were identified as crucial factors influencing grain yield. In the first year, the DZ17-1 and Empire genotypes and in the second year, the DZ17-1, Ceyhan-99, and Din? genotypes demonstrated the highest grain yield potential. Notably, Empire variety exhibited superior performance under dry conditions, underscoring its drought resilience. This study found a linear relationship between grain yield and water use efficiency under rainfed and irrigated conditions, with DZ17-1 achieving the highest yield. These findings highlight the importance of selecting the appropriate wheat genotypes and irrigation strategies to mitigate the effects of drought on wheat production.
