Genetically determined enzyme polymorphism in soy varieties (Glycine max) and in wild soy (Glycine soja)
Analysis of 22 genetic-biochemical systems (42 loci) in 18 varieties of domestic soybean (G. max) and in 3 population of wild soybean (G. soja) was carried out. The part of polymorphous loci (P), intraspecies genetic differentiation (genetic distances--DN) were higher in domestic plants in comparison with wild ones (P = 45%, 17%: DN = 0.038-0.269, 0.059-0129 c86 ). The preferable polymorphism of loci, coding the enzymes of glycolysis and Kreb’s cycle was revealed in wild species. Domestic soybean had more polymorphous enzyme loci, which did not participate in glucose metabolism in comparison with wild species. The presence of the specific part of the gene pool in ancestor species, which was involved in soybean domestication and forming of varieties was discussed.
