A detailed analysis of wild-growing soybean (Glycin e soja Siebold & Zucc., 1845) and 8 cultivars of so ybean (Glycine max (L.) Merrill, 1917), which differ in e arliness and which are recognized in the Amur regio n of the Russian Federation, was made using the methods of b iochemistry and bioinformatics. We systematized the data on revealed electrophoretic spectra of catalases, pero xidases, acid phosphatases, esterases and amylases of soybean seeds of different phylogenetic origin. It is shown that wild-growing soybean has a high adaptive capa city; it is characterized by a small number of enzyme forms (ca talases, peroxidases, acid phosphatases, esterases and amylases). A stable number of forms of the enzymes under study or their increase over the years of cul tivation of varieties demonstrate the high adaptive potential o f varietal soybean. Electrophoretic spectra of the enzymes of seeds can be used as the markers of soybean varieti es adaptation to different growing conditions.
