G × E interaction was also highly significant. High genetic variation for grain yield was found among the genotypes. ResultsĪ set of 270 F 3:6 wheat genotypes in the Nebraska winter wheat breeding program was tested for grain yield in nine environments. Incorporating information from phenotypic and genomic analyses can be useful in selecting the higher yielding genotypes for a group of environments. Phenotypic selection can be misleading due to the environmental conditions. ![]() ![]() Selecting high yielding genotypes that can be used for a target set of environments is needed. One of the main constrains for improving this trait is the G × E interaction (GEI) which affects the performance of wheat genotypes in different environments. Improving grain yield in cereals especially in wheat is a main objective for plant breeders. ![]()
