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.

Abstract. Now for creation of a fertile layer usually use peat-sandy mixes in various parities, which initially do not approach for long-term development of grasses. It leads to that the grassy cover on slopes of roads, city lawns within 2-3 years perishes and is replaced natural by weeds with the vegetation which is not forming strong of sod. The carried out analysis of granulometric structure of soils on which perennial grasses grow, has shown, that as a part of artificial soil the clay containing oozy particles (<0.001 mm) should be an obligatory component. The developed optimising model has shown, that at observance of necessary conditions probably reception artificial soil of middle-loamy granulometric composition possessing optimum physical and agrochemical properties, necessary for long growth of perennial grassy vegetation. As local components it is necessary to use clay, small sand, peat in the parities received at calculation of optimising model. The parity between sand, peat and clay should make 1:2:7. For effect prevention acidification from peat and improvement of agrochemical properties it is necessary to add on 100 kg of a mix of 0.5 kg complex fertilize and 0.2 kg of a dolomitic flour that will provide nutrients to plants while in artificial soil it's own microflora will not start to work.
