New perspective hulled spring oat lines in Omsk agricultural research center

Abstract

The economic, technological, and climatic prerequisites of recent 2 decades determine new relevant requirements for cultivated varieties of agricultural crops. For the stable formation of a high-quality harvest, new adaptive varieties are needed. The purpose of the research was to identify promising hulled oats lines in the competitive nursery of Omsk Agrarian Scientific Center by the main indicators of grain quality and productivity for further research. Omsk hulled lines of spring oats were studied in scientific long-term research (2019-2021). The test object was 8 hulled oat lines, the Orion variety was the standard. The data of the following grain quality indicators were presented: mass fraction of protein, starch and crude fat, 1000 seed weight. The adaptability and stability of these indicators were calculated according to Eberhart and Russell. Mutika 1178, Mutika 1180, Mutika 1195, Mutika 1196, Mutika 1200, Mutika 1202 and Mutika 1205 lines significantly exceeded the standard in protein content in grain (+0.92.6 % to st); Mutika 1147 exceeded the standard in starch content (+1.52.3 % to st); Mutika 1147, Mutika 1195, Mutika 1200, Mutika 1202, Mutika 1205 - in crude fat (+0.61.3 % to st); Mutika 1147 and Mutika 1178 - in 1000 seed weight (+0.93.4 g to st). For further research, the following promising lines are recommended: stable in protein mass fraction (Mutika 1180, Mutika 1195, Mutika 1200, Mutika 1202, Mutika 1205); stable in starch (Mutika 1196), stable in crude fat (Mutika 1147, Mutika 1178, Mutika 1180, Mutika 1195, Mutika 1196, Mutika 1200, Mutika 1202, Mutika 1205) and stable in 1000 seed weight (Mutika 1195, Mutika 1202, Mutika 1205).
