Abstract
This study was conducted over two years in the 2016-2017 and 2017-2018 growing seasons with 13 bread wheat varieties under rainfall condition of Diyarbakir province, Turkey. Trials were designed according to randomized blocks with three replications. Significant differences were determined in all investigated traits (p≤0.01). According to the results of correlation analysis, Grain yield (GY) had a significant positive relationship with heading time and plant height, and a significant negative relationship with protein rate, zeleny sedimentation, and wet gluten. The GGE-biplot analysis revealed the presence of six different sectors with the physiological properties and quality parameters being included in the same sector. It was remarkable that there was a significant negative relationship between hectoliter weight and chlorophyll content and normalized difference vegetation index. Dinc, Gelibolu, Kale, and Aday-12 were prominent genotypes in terms of GY. It was determined that the investigated genotypes showed better potential in the first year of the study, and Aday-12 was the most stable genotype for GY. Based on the results, flag leaf chlorophyll content (SPAD) and normalized difference vegetation index were revealed as important parameters to be considered in quality-based selection. It can be concluded that the genotypes Dinc, Gelibolu, Kale and Aday-12, having a high GY and acceptable quality values, could be recomended cultivated under farm conditions and used as parents in wheat breeding programs
