Genotype selection in plant breeding can be tricky, as it involves choosing the best plants based on multiple traits like yield and quality. A new method called GYT biplot ranks genotypes by how well they combine yield with other important traits, like disease resistance or nutritional quality. This approach is more objective and effective than traditional methods, which rely on subjective weighting of traits. By using an oat dataset, researchers showed that the GYT biplot can help breeders identify top-performing genotypes with a balanced mix of desired traits.
