Our recent studies on developing genomic associated prediction models in wheat based on multi-environmental data have resulted in pedigree-based and genomic-based models that incorporate genotype-by-environment (G×E) interaction terms. However, these models have not yet been widely applied in real breeding programs. Here we report two extensive studies (WAMI phenotyped in 18 environments and International nurseries phenotyped in 136 environments) using pedigree- and markerbased prediction in spring bread wheat and propose using these models in a real breeding program to complement conventional phenotype-based selection.
