Extended Abstract Introduction and Objective: The sunflower is one of the most important oilseed plants in the world and its oil has nutritional and high economic value. Identification and selection of high-yielding genotypes with desirable characteristics are especially important in this plant. Evaluating sunflower genotypes under different environmental conditions would be useful to identify...

Genotype by environment interaction creates intricacy in yield prediction and is a challenge in agronomy and plant breeding. In order to assess yield stability of eight bread wheat genotypes in eight environments (four years under normal and drought stress conditions), eight randomized complete block design with three replications were conducted out in Kerman. Results analyzed as a combined des...

   Testing plant varieties under different regions is necessary to assess their stability. In this study, 17 sugar beet genotypes were evaluated in a randomized complete block design with six replications in five regions including Karaj, Hamedan, Miandoab, Mashhad, and Shiraz. After checking the homogeneity of mean squares in five experiments by Bartlett’s test, analysis of the combined was per...
