Powdery mildew is caused by Blumeria graminis f. sp. tritici and is one of the most important diseases affecting wheat crops. The fungus develops at temperatures of 15-22 ℃ and appears on all plant organs, but most often on leaves. Given the economic importance of wheat, within the Agricultural Research and Development Station Pitesti, in order to conduct research on improving this species, the response of the studied genotypes to the attack of this pathogen is monitored, among other things. In this paper, we present the results obtained under the conditions of the 2023-2024 agricultural year. The aim of our study was to evaluate the response of five genotypes to the attack of powdery mildew (production level and quality indices, respectively protein and gluten content). The studied material was represented by the Trivale variety, as a control variant, and 4 new winter wheat genotypes created within the wheat breeding laboratory, lines A4-10, A44-13, A95-13 and A57-14. The experimental factors were: genotype, seed treatment and type of fertilization. The results obtained showed that line A4-10 presented better tolerance to powdery mildew.
