Abstract :The study was conducted in randomized complete block design with four replications at two locations insert ignore into journalissuearticles values(Sanliurfa and Diyarbakir); under rainfall conditions during 2013-2014 growing season. The purpose of the study is to determine the bread wheat genotypes with high yield, large adaptation ability and high grain quality. Twenty advanced bread wheat lines and five check varieties were used as material. The data were evaluated by using variance and GGE-biplot analysis methods. Significant differences among genotypes were determined for test weight insert ignore into journalissuearticles values(TW);, thousand grain weight insert ignore into journalissuearticles values(TGW);, grain yield insert ignore into journalissuearticles values(GY); and heading time insert ignore into journalissuearticles values(HT); at the significant level of 1%, while, less significant levels insert ignore into journalissuearticles values(p<5%); were found for wet gluten content insert ignore into journalissuearticles values(WG);, zeleny sedimentation insert ignore into journalissuearticles values(ZS); and protein content insert ignore into journalissuearticles values(PR);. According to GGE-biplot analysis results, positive correlations were determined between TW and TGW, and also PR, WG and ZS. It has also been determined that there is a negative relationship between HT and TW, TGW. According to the stability graph, the genotypes of G23 and G8 were found to be highly efficient and moderately stable and both could be candidate varieties. Additionally, Dinç variety and G11 advanced line can be used as genitor in bread wheat breeding programs for grain yield and quality.
