The results of the evaluation of the genetic cherry collection of the Republican Unitary Enterprise “Institute for Fruit Growing” for winter hardiness, resistance to coccomycosis and large-fruited are presented. Among the studied 213 cherry accessions 6 highly winter resistant, 105 resistant to cherry leaf spot, three genotypes with very large fruits (varieties Krupnoplodnaya, Lyubava Donetskaya, Legenda Mliyeva, the fruit weight of which exceeds 8.3 g) and 11 accessions with a fruit weight exceeding 7.0 g (varieties Krasavitsa, Dar Mlieva, Donetskaya Krasavitsa, Donchanka, Sashenka, Ugolek, Yaroslavna, Lambert Compact, hybrids 10/98, D-7-87, № 5) were identifi ed. Two sources (varieties of sweet cherries of the Belarusian breeding Severnaya and Syubarovskaya), combining high winter hardiness and resistance to coccomycosis, were revealed. On the base of the identified genotypes a characteristic collection of sources of winter hardiness, large-fruited and resistance to coccomycosis has been formed for use in the new sweet cherry breeding program.
