Abstract
Oilseeds are one of the most important sources of energy worldwide. Sunflower is an important crop with nutritional and high economic values. Sunflower is one of the most important oilseed plants in the world, whose seeds contain 26-50% oil and 20-27% protein. By using new and high-yield hybrids, the economic performance of sunflower can be increased. Evaluating new sunflower hybrids under different environmental conditions is essential in identifying and selecting superior genotypes with high and stable yield potentials. Genotype × environment interaction effects are important limiting factors in introducing new cultivars. Various methods have been introduced to evaluate the interaction effects, each of which examines the nature of the interaction effect from a specific point of view. The GGE-biplot graphic method is an approach with suitable efficiency to investigate the interaction effect of genotype × environment and provides good graphical information regarding genotypes and environments. The aim of this study was to investigate the interaction effect of genotype × environment using the GGE-biplot graphic method in order to evaluate genotypes, environments and relationships between genotypes and environments and finally to identify stable genotypes with high seed yield under different environmental conditions in sunflower.
