Investigation of Bread Wheat Genotypes with Different Characteristics by Physiological and Quality Traits

Instruments measuring spectral reflectance are extensively used by many researchers to determine the relationship between grain yield insert ignore into journalissuearticles values(GY);, quality, and physiological traits of bread wheat genotypes at different developmental stages. This study was carried out under rain-fed conditions in 2019-2020 and 2020-2021 growing seasons in Muş province. The experiment was set up in a randomized block experimental design with 3 replicates. Except to flowering stage chlorophyll content insert ignore into journalissuearticles values(FSC);, statistically significant differences were determined among genotypes at the level of p≤0.01 in all examined characteristics. More explicitly, G6, G8, G10, Müfitbey, Hanlı and Metin in terms of GY; Cemre, Kenanbey and Bezostaja 1 as regards quality traits; Ekiz, G8, and G9 with regard to physiological traits were found as significant genotypes. Biplot model analysis, used to determine genotype-trait and stability relationship, showed that thousand grain weight insert ignore into journalissuearticles values(TGW); and plant height insert ignore into journalissuearticles values(PH); were positively associated with both GY and Normalized Difference Vegetation Index insert ignore into journalissuearticles values(NDVI);. GY was found to be related to canopy temperature insert ignore into journalissuearticles values(CT); and heading time insert ignore into journalissuearticles values(HT); negatively. Notably, NDVI were positively related to protein ratio. Hanlı, Metin, G6, G8, and G10 were established as the high-yielded stabile genotypes which are least affected from environmental conditions
