- The successful parallel selection of homozygous parental genotypes (based on traits regulated by additive genes controlling phenology and plant height) and components revealing a high heterosis effect (the choice based on the highest values of spike-yield-related traits revealed by heterozygous genotypes) using GWAS.
- Demonstrating that the application of clustered markers for the choice of genotypes in multi-feature processes may be more efficient than classic selection based on single marker polymorphism (SNP)
- Validation of the GWAS results using post-registration trial data.
