The purpose of the given work was to identify strawberry varieties, resistant to powdery mildew. Research was carried out in 2010-2016 at Lisavenko Research Institute of Horticulture for Siberia according to the programme and method of variety-study of fruit, small fruits and nut crops. The objects of research were 107 strawberry varieties of native and foreign breeding of plantings of 2010, 2011, 2012, 2013, 2014 years.

Unresistant to powdery mildew were the varieties Darenka, Krasnaya perchatka, Podolyanka, Rusanovka, Yaponka, which on average were affected by 0,9-1,5 points, maximum - 3,5 points. There were 44 varieties, including Aquarelle, Barabinsky, Bogota, Duet, Pervoklassnitsa, and others, with good fi eld resistance to this disease (average affection 0,5-1,0 scores, in the epiphytotic years - not more than 2,0 points). As a result of many years of research, 18 varieties were identifi ed (Artemis, Vima tarda, Desna, Kruzader, Mlechny put, Omskaya raniya, Penelope, Reritan, Tago, Tantalon, Tanyusha, Feyerverk, Kholidey, Tsaritsa, Tsarskosel’skaya, Tsunami, Shuekrop, Estafeta), resistant to powdery mildew, in which the lesion in epiphytotytic years was no more than 1,0 points.
