Foliar diseases attack common winter wheat throughout Europe, causing enormous economic damage to this crop. The parental forms and F1 hybrids of wheat under the conditions of the experimental field (2023 year) differed significantly based on the attack of foliar diseases, in particular, yellow rust and septoriosis, which made it possible to classify them into clusters with different degrees of similarity/difference of the tested forms. Most of the F1 hybrids of wheat registered a lower degree of attack of the mentioned diseases, forming a cluster separate from the parental forms, which offers chances to identify resistant forms in progeny populations.
