Virus-free clones were selected for each variety. Based on the sequencing of genomic fragments, the molecular-genetic characteristics of individual isolates of Prunus necrotic ringspot virus, Prune dwarf virus, Plum pox virus, and Raspberry bushy dwarf virus were studied. Variety-specific methods of propagation in tissue culture conditions for raspberry varieties, stonefruit rootstocks, hazelnut varieties, and Actinidia have been developed. The activity of pyrimidine derivatives as plant growth stimulators has been studied. Virus elimination methods for certain viruses that infect raspberries have been developed. The allelic state of the S-locus and the cross-incompatibility group was established for 120 samples of sweet cherry varieties and wild cherry forms. 17 different S-alleles were identified. The analyzed varieties of sweet cherry were classified into 17 known groups of cross incompatibility. Product Description popup.authors Vasyuta Svitlana O Vysoven Volodymyr I. Danilishyna Olga M.
