Oats - important fodder and food crop. Its value primarily lies in the wide environmental adaptability, the content in grain protein, carbohydrates, fats, vitamins, microelements, biologically active substances in optimal combination of the necessary human and animals for normal functioning and good health. In Russia, mainly cultivated spring oat and its area is concentrated in the Siberian, Volga and Central Federal districts. The share of the North Caucasus Federal district in the production of this crop is only 1.5 to 3.2 %, and the Krasnodar Territory and less. Recent years significantly increased the demand of agricultural producers for oats. Released varieties is extremely unstable for years of productivity. In 2014 LLC "Agrostandart" passed the State testing two varieties of spring oats Landing and Assol. Landing obtained by individual selection from Swedish varieties Magne. Species - aristata. Panicle erect, compressed, panicle length the average. Plant height of 60-95 cm. Variety is highly resistant to lodging. Productive tilling capacity of 1.0-1.7 stems. Mid-season. 1000 grain weight is 27.3-39, 6 g. By nature of the grain exceeds Valdin 765 on the 15 grams. This variety has good field resistance to crown rust, resistant to almost dusty head. The average yield over 4 years was 37.3 centner from hectare, which is higher than the standard 11%. The maximum yield obtained by predecessor white mustard 53, 8 centner from hectare. Variety Assol the result of individual selection of varieties Krasnodarsky 73. Kind – mutica. In the growing period refers to mid-season varieties, panicle spawns and matures at the level of Valdin 765 and one day earlier than the parent varieties.

Panicle erect, pyramidal, polygala, loose, average length 20-25 cm of the Kharkiv Grain type, small, weight of 100 grains of 23.2 is 34.7 g. at the level of the standard. Panicle length, number of grain / panicle, weight of grain per panicle and the grain shows better stability of varieties to abiotic and biotic stresses.
