Abstract
Wheat is the main food crop in Russia, but from 10 to 20% of the crop is lost annually due to its damage by fungal, viral and bacterial diseases. Rust diseases and powdery mildew are the most economically significant diseases that have caused yield losses in the main grain-producing regions in recent years. Introduction of resistant wheat varieties into production allows to significantly reduce the use of pesticides, improve the phytosanitary and ecological situation in agrophytocenosis, and increase the sanitary and hygienic quality of products. In this connection, creation of spring wheat varieties with dominant traits to ensure and preserve food security is of particular relevance for Samara region. An important task is to obtain varieties with high yield and resistance to powdery mildew and rust types. Research objective: to study the resistance of different varieties of mild spring wheat to powdery mildew and brown rust in the forest-steppe of the Samara region. The varieties of spring wheat Kinelskaya 59, KinelskayaNiva, KinelskayaOtrada were taken as an object of research. Materials and methods. The studies were conducted on the fields of the Volga Research Institute of Breeding and Seed Production named after P. N. Konstantinov. The spring wheat varieties KinelskayaNiva and KinelskayaOtrada were more resistant to leaf disease pathogens in 2020, while Kinelskaya 59 was less resistant. Despite the high percentage of disease prevalence, these varieties have high yields, indicating field resistance. The data obtained can serve for the implementation of spring wheat breeding programs for resistance to powdery mildew and brown rust.
