The results of studies on the stability of winter wheat varieties of domestic and foreign breeding against pathogens of hard soot on an artificial infectious background are presented. Among varieties of domestic breeding, the Slavna variety, which was not affected by the disease for three years of testing, was very resistant. High resistance to hard soot was shown by 8 varieties: Smuglyanka, Novosmuglyanka, Oktava, Spasivka, Liga Odes’ka, Katrusya Odes’ka, Zolotokolosa, Pryvablyva. The damage rate of these varieties did not exceed 5 %. Persistent were the following varieties: Zisk, Nota Odes’ka, Fermerka, Konka, Pylypivka, Boria, Lira Odes’ka, Gilea. Of the varieties of foreign breeding showed a very high resistance to the disease variety Vita, and high – such varieties as Sotnitsa, Grom, Skipetr, Vasa (Russian selection) and Salem (Canadian). Irishka and Krasnodarskaya 99 varieties were stable. Their use in breeding processes will increase resistance to hard soot in newly created varieties.
