Evaluation of winter triticale source material for resistance to leaf pathogens

Winter triticale combines high grain and green mass yields with resistance to adverse climatic conditions.However, one of the main factors limiting its yield is its susceptibility to pathogens, including powdery mildew and brown rust.To ensure stable production and increase agricultural efficiency, it is important to develop and introduce disease-resistant varieties.Breeding such varieties allows to reduce the use of chemical protection products, while maintaining high yields and reducing the negative impact on the environment.The aim of this study was to determine the level of resistance of winter triticale collection samples to the main leaf diseasespowdery mildew and brown rust.The study of different triticale samples differing in ecological and geographical origin allowed us to identify genotypes with high rates of complex resistance.According to the results of three-year studies (2022-2024), samples (Urahan, Sybyrskyi, Soiuz, Tornado, Tsekad 22 and Bohodarske) with high indexes of complex resistance were identified, indicating their potential for use in breeding programs.
