Hybridization and Genetic Control of Esterase in Apricot
Cytology and Genetics 2002, v 36, number 3, 17-21
Inheritance of esterase was studied in nine segregating progenies. It was established that fast migrating components are controlled by two loci, Est-1 (monomeric a-esterase) and Est-2 (dimeric b-esterase). Their polymorphism is determined by three active alleles, a, a¢, b for Est-1 and a, b, c for Est-2, respectively. Allelic frequencies and heterozygosity of loci in ecological-geographical groups and Central Asian subgroups were estimated. Genetic control of esterase in stone fruits was proposed for the first time.
