| Summary: | A new direction of agribusiness has been formed in the modern agricultural industry. This is expressed in the appearance of highly specialized enterprises working in the field of production of high-quality seeds of agricultural crops. The use of electrophoresis method in varietal identification is a new technology in domestic agribusiness. The purpose of the research was to study the electrophoresis role of prolamins in varietal identification of crops for high-quality seed material. The laboratory of varietal identification of seeds analyzed 47 varieties of oats Russian selection. On the basis of data on the component composition of avenin, varieties with a high level of intersort genetic differences were identified: Megion, Fobos, Local (K-8427), Uspekh, Otrada, Pushkinskij. Groups of samples with identical component composition of prolamins were found. Their genetic formulas of avenin have the following form: Avn A2B4C2, Avn A4B4C2, Avn A2B4C1 or Avn A2B1C3. It is established that the method of electrophoresis of oat prolamins allows effectively distinguish varieties belonging to the same variety and indistinguishable by morphological features. Implementation of a system of regular laboratory control of purity and compliance of original and reproductive oats seeds by electrophoresis of prolamins is necessary to improve the competitiveness of Russian grain production in the world market.
