Abstract
Forms of the subgenus Typocerasus Focke with high winter hardiness and disease resistance, with improved consumer qualities, have been identified. Select the best genotypes to form a characteristic collection and improve the breeding process of cherries (Cerasus vulgaris Mill.) and sweet cherries (Cerasus avium L.).
Winter hardiness was studied in the field over many years of experience in years with the most critical temperature conditions for cherries. Resistance to fungal diseases Monilia cinerea Bonord and Coccomyces hiemalis Higg. studied during the years of epiphytotics.
The results of a study of winter hardiness and resistance to fungal diseases of 43 interspecific hybrid forms of the subgenus Typocerasus Focke are presented. As a result of the study, 15 forms of East Asian cherry were selected, combining a high level of winter hardiness of vegetative buds, bark, wood and flower buds and high resistance to moniliosis and coccomycosis, which formed the basis of the characteristic collection. The consumer qualities of the studied forms are determined.
The identified cherry species and hybrids are of interest for the creation of winter-hardy cherry varieties with high resistance to fungal diseases on a fundamentally new genetic basis.
