stability performance of bread wheat (triticum aestivum l.) lines

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.
