Viewed : 239 - Downloaded : 238 Genotypes may show different performance in different environmental conditions. Registration trials of cool season cereals are carried out in our country as a regional. Aegean and Southern Marmara regions were considered as separate regions until the year 2009. After that they are combined. The aim of this research was to determine the grain yield stability and quality characteristicsof Ziyabey 98, BasriBey 95, Gönen 98, Tahirova 2000, Pamukova 97 and Hanlı bread wheat varieties which were registered separately for both regions. Differences of opinion regarding the integration of the region continues today. Furthermore, this study; a general assessment is important in terms of retroactively be made. Experiments were established in randomized completely block design with four replicates between the years 2010-2013. Mean yield of varieties, regression coefficient (b), regression line intercept (a), determination coefficient (R2) and coefficient variation (CV) were evaluated as stability parameters. According to the result of stability parameters, Ziyabey 98, BasriBey 95 and Hanlı varieties came to the fore in grain yield. The highest value in a thousand kernel weight was obtained in Tahirova 2000. There was no statistical significance between varieties in hectoliter weight. Pamukova 97 was showed the highest value in terms of protein content, zeleny sedimentation and alveograf energy value. Keywords : Bread wheat, grain yield, stability parameters, quality
