The Chelyabinsk Research Institute of Agriculture (CRIA) conducts targeted breeding for the complex resistance of soft spring wheat to biotic and abiotic stress factors, with the involvement of alien translocations donors. At the same time, the virulence of the pathogen populations is monitored. The purpose of these studies is to study disease resistance and to characterize economically valuable traits in 60 introgressive lines created in the CRIA, and to assess their influence on the variability of pathogens populations for virulence. Using molecular markers, the high genetic diversity of the studied collection of introgressive breeding lines for effective alien resistance genes was confirmed. According to the field and laboratory studies, promising lines were identified (Lutescens (Lut.) 26708, Erythrospermum (Erythr.) 26725, Ferrugineum (Ferr.) 26727, Ferr. 26752, Ferr. 26757, Erythr. 26762, Erythr. 26775, Lut. 26720) These lines combine multipathogen diseases resistance with a complex of economically valuable characteristics (yield, grain quality). There was no effect of introgression lines of spring wheat on the variability of the pathogen population for virulence.
