Abstract:

In this study, it was aimed to determine the yield and quality characteristics of 32 advanced lines and three bread wheat varieties (Tosunbey, Saggitario and Ceyhan-99) in irrigated conditions in Diyarbakir province ecological conditions and to evaluate the relationship between line and characteristics with GGE biplot analysis technique. The experiment was carried out according to Augmented Trial design in the 2020-2021 growing season at Dicle University, Faculty of Agriculture, Field Crops Department, Research and Application area. In the study, the number of days of heading, plant height, spike length, number of grains per spike, thousand grain weight, hectoliter weight, grain yield and grain protein ratio were investigated. In the results of study, grain yield and grain protein ratio varied between 463.1-920.5 kg da-1 and 13.5-18.3%, respectively. Tosunbey variety (920.5 kg/da) given the highest value for grain yield, and H-20 line showed the closest value to this variety with 890.0 kg/da. According to biplot analysis, the number of days of heading, number of grains per spike, grain yield, grain protein ratio and plant height were in the same group, while thousand-seed weight, spike length and number of grains per spike were in a separate group. Hectoliter weight alone formed a separate group. The lines (H-9, H-10, H-15, H-18, H-20, H-27 and H-31), standout in the characteristics examined as a result of the research, will contribute to the breeding bread wheat suitable under irrigated growing conditions.
