The aim of the study was to determine the structure of GEI in the investigated parameters and to investigate the performance stability of durum wheat varieties using the GGE biplot and AMMI analysis method. The study was carried out in four different locations (Diyarbakır-1, Diyarbakır-2, Hatay, and Şanlıurfa) using 31 durum wheat genotypes under rainfed conditions. Field experiments were conducted in a randomized complete block design with three replications. As a result of the study, it was determined that there was a significant difference between locations in terms of grain yield. The highest grain yield was obtained from Diyarbakır-1 (6797 kg ha-1) location, followed by Hatay (4584 kg ha-1), Diyarbakır-2 (2512 kg ha-1) and Şanlıurfa (2026 kg ha-1), respectively. Significant variations in grain yield were detected among the examined genotypes, and Artuklu and Zühre had the highest grain yields (4774 and 4501 kg ha-1). Again, Artuklu and Zühre were the most stable varieties in terms of their performance in different locations. Diyarbakır-1 has come to the fore as the location where the variation between genotypes can be best detected. As a result, more data should be provided to plant breeders in the selection studies by considering the irrigated conditions as a factor in the studies to be carried out and determining the stable cultivars in terms of grain yield in both precipitation-based and irrigated conditions.
