To reduce the pesticide load in industrial plantings, it is necessary to use pathogen-resistant varieties when establishing orchards. The problem of obtaining stable, large-fruited, adaptive varieties is acute, since there are practically no genotypes in the existing assortment that combine a complex of economically valuable traits with resistance to diseases. The isolation of new resistance genes in wild forms and the creation of genotypes resistant to fungal diseases on their basis is possible through the use of remote hybridization. Interspecific hybrids with sweet cherry were obtained at the Krymsk EBS, VIR Branch, which combine resistance to coccomycosis and increased fruit size. These genotypes are complex sources of traits for further breeding work in obtaining adaptive, large-fruited genotypes. The work carried out proves that the use of interspecific hybridization makes it possible to obtain genomes highly resistant to coccomycosis.
