In addition to being a basic nutrient in nutrition around the world, wheat is a strategic product due to its high adaptability and potential to be processed into different products. Bread wheat represents a proportional share of around 95% in world wheat production. The research was carried out in Diyarbakır-Hazro conditions in the 2011-2012 growing season according to the randomized block design with 4 replications under rainfall conditions. The experimental material consisted of 20 advanced bread wheat lines and 5 control varieties (Nurkent, Pehlivan, Cemre, Sagittario and Ceyhan-99). Except for grain yield, all examined traits were determined to be significant at p relationship with polygons, sectors and vectors, PC1 explained 35.82%, PC2 27.14% and PC1+PC2 62.96% of the variation between genotypes for the examined traits. While grain yield and heading time were in different groups and sectors, plant height and thousand grain weight were determined to be in the same group and sector. G1 (285.7 kg.da-1 ), G4 (297.5 kg.da-1 ) and G12 (279.4 kg.da-1 ) were the best genotypes in grain yield, G9 (37.3 g) and Pehlivan (37.8 g) were the best genotypes in thousand grain weight. The polygon plot showed that genotypes in sectors where no traits were present did not stand out in terms of any trait. In the study, it was determined that the Hazro location is different from Diyarbakır Center in terms of both climate structure and altitude, and the breeding program based on location-focused variety development is important. In this context, it was concluded that it would be beneficial to continue studies at the same location, and that GGE biplot analysis was distinctive in determining the genotype trait and trait-to-trait relationship and was easy to use in selection.
