Global climate change has a major negative impact on sustainable crop production. Drought and heat stress during wheat growth and development are the most important factors affecting wheat yield and quality. The study was carried out in Diyarbakır in the 2023 production season. In the study, 14 genotypes obtained from International Maize and Wheat Improvement Centre (CIMMYT) and Empire Plus, Hilar and Amida were used as standard varieties. SPAD (Flag leaf chlorophyll content), NDVI (Normalized Difference Vegetation Index), plant height, grain yield, 1000-grain weight, protein content and starch content were investigated. Significant differences were found among genotypes for all traits, with the exception of NDVI values. Due to spring sowing, there was a noticeable drop in both grain yield and 1000 grain weight values, and the plant height was severely reduced.  Protein and starch content values increased. According to correlation analysis, there was a positive significant relationship between SPAD and 1000-grain weight and protein content and a positive significant relationship between NDVI and grain yield. The biplot study indicated that genotypes G13, Amida, and Empire Plus exhibit exceptional suitability for heat-stressed circumstances. These genotypes can be utilized as parental lines in breeding research due to their stability and remarkable performance in terms of grain yield potential.   The findings indicate that farmers who are have to sow wheat in spring can achieve satisfactory yields as long as they engage irrigate.
