The study was conducted in the Thrace Region in 2019 and 2020. Fifteen elite lines and 10 varieties of durum wheat were used as material. The aim of this study was to determine the stability of elite lines and varieties by using the graphical AMMI and GGE biplot analyses. Elite lines 3, 4, 5, 7, 8, 9, 10, 12 and 15 and varieties Cabato and NKU Ziraat had values above the general mean. The results for grain yield of elite lines in this study show that the grain yield potential of elite lines selected as breeding material was good, and that the selection was successful. When the stability of the genotypes was evaluated, 3 of the 8 environments had positive effect on grain yield, while 5 of them had negative effect on grain yield. These data reveal the importance of identifying suitable environments for high grain yield in durum wheat. Among the durum wheat genotypes examined, elite lines 7 and 4 had better stability and grain yield for all environments. When the genotypes were examined separately for each environment, elite lines 3, 9 and 10 showed the most superior characteristics for environments 1 and 4, while elite lines 12 and 15 were most suitable for environments 7 and 8.
