Popis: Features of the analyzed allele distribution in domestic and foreign varieties are revealed on the basis of apple variety and shape polymorphism in alleles of genes associated with shelf life (Md-ACS1 and Md-ACO1) and fruit quality (MD-Exp7). Two allelic states have been revealed for the Md-ACS1 gene. With regard to the foreign selection Fuji and Gala varieties, the Md-ACS1 gene is in a homozygous state. In the examined varieties, the Md-ACO1 gene is represented by two allelic variants, and the MD-Exp7 gene of expansin biosynthesis is represented by three allelic forms. Allele 1 is responsible for a lowered level of expansin synthesis and is identified in wild apple-tree species (Chinese Golden Apple, Tayozhnoye, Caucasian Self-Fruitful).
