SELECTION OF SOURCES OF WINTER HARDINESS, RESISTANCE TO CHERRY LEAF SPOT AND LARGE SWEET CHERRY FRUITS

The results of the evaluation of the genetic cherry collection of the Republican Unitary Enterprise “Institute for Fruit Growing” for winter hardiness, resistance to cherry leaf spot and large-fruited are presented. Among the studied 213 cherry accessions were identified six highly 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 genotypes 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. Two sources – Belarusian sweet cherry varieties ‘Severnaya’ and ‘Syubarovskaya’ were identified, combining high winter hardiness and resistance to cherry leaf spot. A characteristic collection of sources of winter hardiness, large-fruited and resistance to cherry leaf spot has been formed based on the selected genotypes for use in the new sweet cherry breeding program.
