The primary aim of plant breeding is to improve stability in yield and to obtain varieties with good quality. For this reason, a study of wheat varieties was conducted in 2010, 2011, and 2012 at the Agricultural Application and Research Center fields of the Uludag University, Agricultural Faculty, in Bursa/Turkey. In the study, 22 advanced lines of bread wheat and Gonen, Pehlivan, and Flamura cultivars as controls were examined in a 3-year experiment. In each year, the experiment was conducted in randomized block design with three replications. The effects of cultivars, environment, and genotype×environment interactions were evaluated. Results of the study permitted us to distinguish three lines, namely, (Gx22-1)-4, (Gx22-1)-6, and (GxK) which were characterized by higher adaptation capabilities and stability than those of the other genotypes.
