RESISTANCE OF BARLEY VARIETIES TO MAJOR FUNGAL DISEASES

Abstract

Barley is one of the most common grain crops in the world, but on the territory of Kazakhstan, the culture has acquired great agricultural importance due to its unpretentiousness in production in a difficult climate. One of the promising areas in agriculture is the identification of varieties resistant to fungal diseases. The main aspect when using resistant varieties of barley is to improve the quality of products due to the partial or complete rejection of chemical processing. In 2021-2022 On the experimental field of the Kazakh Research Institute of Agriculture and Crop Production, a field assessment was made of the resistance of 46 varieties of winter and spring barley of domestic origin to the most common fungal diseases in Kazakhstan (net spot, brown spot, rhynchosporia and powdery mildew). According to the results of phytopathological assessment, sources of resistance to major fungal diseases were selected among barley varieties. 7 varieties of winter and spring barley were found, resistant to several fungal diseases. The identified accessions and varieties of barley, resistant to both one and two or more pathogens, can be purposefully used in breeding programs to create resistant varieties of barley.
