The generalized results of a comprehensive long-term assessment (2015-2019) of biochemical and technical indicators of the quality of apple fruits of promising varieties (Malus domestica x Borkh.), including: the valuable initial parental forms and new varieties of regional selection, different in ploidy and genetic origin are presented, grown in the conditions of the South of Russia. This work used the generally accepted modern methods and programs for the variety study of fruit plants developed at the North Caucasian Federal Scientific Center for Horticulture, Viticulture, Wine-making (NCFSCHVW). The aim of the study was to select the source material of the apple fruit quality, which is valuable for the breeding, and the sources of the target traits based on the analysis of longterm data on the assessment of the biochemical composition of promising varieties of different ploidy and genetic origin. As a result of the comprehensive assessment of the main indicators of the quality of apple fruits in a varietal section, the sources of significant traits of apple tree for breeding use were identified: large-fruited, bright red and pure yellow color, improved chemical composition of fruits. According to the data of a longterm studies of the quality indicators of the apple fruits of introduced varieties and varieties of selection of the FSBSI NCFSCHVW, genotypes with an improved biochemical composition were identified for the use in the selection process: diploids: Champion, Orpheus (sugar content 10.5% and 10.8%, respectively); triploids: Soyuz, Vasilisa and the diploid variety Fortuna (vitamin C - more than 10.0 mg / 100 g); diploids: Margo, Vasilisa (P-active substances - more than 110.0 mg / 100 g).
