In 2020, resistance to leaf and yellow rust in 62 varieties of winter soft wheat recommended for cultivation in the Central Chernozem region of Russia was characterized. Varieties resistant to two rust species (group resistance) (16%) or to one of them (18% to yellow, 1% to leaf rust) have been identified. Moderate level of group resistance to both types of rust (disease severity up to 15%) was shown for varieties Moskovskaya 56, Moskovskaya 70 and Latynevka. Varieties Bogdanka, Volzhskaya 100, Volzhskaya K, Izyuminka, Lidiya, Odesskaya 200, Rubin were characterized by moderate resistance to yellow rust and weak susceptibility to leaf rust. For the first time in the conditions of the Tambov region, the virulence of the yellow rust pathogen was studied, and racial composition was characterized. Two races 79E190 and 15E144 were revealed among Tambov isolates of P. striiformis by the use of a set of differential lines in the virulence analysis. All the isolates were avirulent to Avocet lines with genes Yr5, Yr10, Yr12, Yr17, Yr24 and YrAR.
