Abstract
This study was carried out under rain-fed conditions in 2019-2020 and 2020-2021 growing seasons in Muş, Turkey. The experiment was set up in a randomized block design with 3 replicates. Significant statistical differences were determined between varieties (p≤0.01 or p≤0.05) in grain yield (GY) and all examined physiological characteristics, except GS77 period Normalized Difference Vegetation Index (NDVI). While Erciyes, Çatalhüyük, Asutay and Aydanhanım barley cultivars were high yielding, and Bozlak was determined to be both high yielding and the most stable barley variety. In the correlation analysis, a positive and significant relationship was determined between GY and NDVI in the GS83 (r=0.298*) and GS85 (r=0.366**) periods. The GGE biplot model, visually presented the negative correlation between canopy temperature (CT) and GY. It was concluded that the selection of genotypes with high biomass, high flag leaf chlorophyll content, low canopy temperature and stable at the same time is important.
