Abstract. The studies aimed to assess the resistance of genetically diverse samples of common wheat (Triticum aestivum L.) from the world collection of the Vavilov All-Russian Institute of Plant Genetic Resources in the case of the damage of the local population by powdery mildew for the isolation of immune samples or samples characterized by a high field resistance under conditions of the Novosibirsk region. These samples can be used in the breeding of new disease-resistant varieties. In 2008–2020 we evaluated 657 collection samples of common wheat affected by powdery mildew against a provocative infectious background in an isolated nursery. In 2018–2020, the wheat samples that were resistant in 2008–2017, containing Pm7 (Thatcher Lr25) and Pm17 (KS93U50 and KS93U62) genes, and the Pm8 + Pm17 gene combination (Amigo, KS90WGRC10) lost their immunity to Blumeria graminis. Immunity to the population of the Blumeria graminis was characteristic of 48 varieties of common wheat from 13 countries. A high level of field resistance (leaf surface damage varied from 1% to 10%) was characteristic of 23 varieties from eight countries. Effective protection of varieties and lines from damage by the fungal population was provided by Pm6Agi1, Pm6Agi2, PmKu, and Pm4a genes, as well as combinations of the Pm6Agi2, Pm38 and Pm1, Pm3d, and Pm6 genes. Samples Belyanka, Voevoda, Favorit, Tulaykovskaya 10, Novosibirskaya 61, Tulaykovskaya Zolotistaya, Tulaykovskaya 100, Tulaykovskaya 110, Tulaykovskaya 5, Lutestsens 13, Ekada 85, LT-2, Mertsana, Toma, Poema, Lyubava, Laska, Vasilisa, Sirael, Sonett, Canon, SW Vinjett, SW Milljet, SW Estrad, SW Vals, SW 17283, Lavett, Swedjet, SW Kronjet, SW Kungsjet, SW Kadrily, Khapli, Quattro, Tybalt, Banti, Brawura, Izera, Garenda, KWS Torridon, Cub, Amaretto, KVS Akvilon, KVS Dzhetstrim, Kvintus, Likamero, Kalikso, CS2A/2M, and PS 133 can be used to breed varieties resistant to powdery mildew in the Novosibirsk region.
