Genomic analysis of interspecific hybrids of diploid plums on the basis of their genealogy

Discusses the proposed methodology for the classification of remote hybrids of woody plants, based on the establishment of genealogy and nuclear-cytoplasmic formulas. For the establishment of nuclear-cytoplasmic formulas can be calculated for each hybrid to the average fraction of the genomes of the original parents-telsky species and record the species of the cytoplasm. The study of the genealogy of 696 varieties of diploid plums was carried out, for 425 varieties nuclear-cytoplasmic formulas were established, based on the analysis of which 13 types of hybrids were identified, including 88 groups of varieties. The basis for the selection of a group of varieties is the uniformity of nuclear-cytoplasmic formulas. This classification greatly simplifies the selection work.
