GENETIC DIVERSITY OF SIBERIAN SPRING BARLEY VARIETIES IN ENSURING ECOLOGICAL STABILITY OF AGROCENOSES IN EASTERN SIBERIA

The article discusses the results of genetic monitoring of Siberian forms of barley and breeding material for allelic variants of hordein blocks. The research was carried out at the Krasnoyarsk Research Institute of Agriculture from 1988 to 2022. The established genogeographical feature of hordein alleles allows, when determining the compliance of selected forms with local agroecosystems and selection directions, to focus on the characteristic (adaptive) alleles of barley (for specific regions) and noted for their relationship with certain economically valuable indicators.
