Assessment of variability of productivity traits and biochemical composition of apple tree varieties and forms, selection of the Orenburg branch of the federal state budgetary scientific institution federal research center of horticulture

Currently, new varieties are subject to strict requirements for adaptability, productivity, commercial and consumer qualities of fruits. In this regard, it is important study the interaction genotype apple tree forms with climatic conditions, also necessary assess genotypic variability economically valuable traits focused on identifying genotypes characterized by stability fruit quality in growing conditions. The examined 12 tree, selected Orenburg branch FGBNU FNTs Horticulture. following signs were studied: useful ovary (%), number fruits (pcs.), average weight (g), productivity (kg/d), sugar content fruits, soluble solids, ascorbic acid, determination titrable acidity. used mathematical models two-factor variance cluster analysis Ward method. Statistically significant differences observed between first third, second third clusters (t = 4.01 4.35, at p<0.01, respectively), as well 9.19 p<0.01), 8.7 p<0.01).
