Valuable oat varieties identification for food purposes under the southern Western Siberia conditions

The purpose of the study is to identify valuable cereal forms of filmy and naked oats grown in the conditions of the southern forest-steppe of Western Siberia. The study was conducted in the the Grain Quality Laboratory of the Omsk Agricultural Scientific Center in 2018-2021. The evaluation of cereal properties of 30 samples of filmy and naked oats of the laboratory of selection of grain forage crops was carried out using the methods of the State Commission for variety testing of agricultural crops and developed in the laboratory of grain quality. The protein content in the grain was determined by the Kjeldahl method modified by M.I. Bazavluk. 12 promising forms of hulled and 4 naked oats were selected. The features of assessing the quality of grain of various forms of oats are clarified. The strength and direction of the connection between the features that determine the quality of oat grain are analyzed. It was found that the advantage of naked forms in terms of protein content in the grain was 40.8 %; nature of grain - 40.3; cereal yield - 26.6 % in comparison with filmy varieties. At the same time, filmy forms were distinguished by larger grains with a lower content of fine fraction (by 81.3 %) and a yield of 29.9 % more than that of naked samples. It was established that the yield of cereals in filmy forms is associated with the nature of the grain and its evenness, and in naked forms - only with the nature of the grain. The relationship between the yield of cereals and the protein content in the grain was determined. It is recommended to use the high-yielding variety Uran for the production of high-quality cereals in the zone of the southern forest-steppe of Western Siberia, and from the naked forms - the larger-grained variety Tarsky naked, which is characterized by high yields, protein content in grain, nature and a low proportion of fine grains. Of the breeding lines, membranous Mutika 1178, Mutika 1147 and naked forms Inermis 1194 and 1189 had preference.
