IRTYSH 13 is a spring oat (Avena sativa L.) variety distinguished by high adaptability and stable yield under various climatic conditions, particularly in Western Siberia. This variety is characterized by a medium-late maturity period, lodging resistance, and medium drought tolerance, making it a reliable choice for cultivation in regions with a variable climate. The mass of 1000 grains varies from 34 to 44 grams, indicating good grain quality.
IRTYSH 13 belongs to the mutica type and is a fodder variety with high protein content in the grain — from 9.1 to 11.5%, which enhances its nutritional value. The variety demonstrates high productivity both in terms of green mass and grain yield, reaching an average yield of about 35.5 centners per hectare. Thanks to its unpretentiousness to growing conditions, it is recommended for cultivation in various regions, including the Omsk, Tomsk, and Yaroslavl regions.
Special attention should be paid to the variety's disease resistance: IRTYSH 13 shows resistance to powdery bunt, but is susceptible to crown rust and red-brown blotch. This requires consideration when planning agrotechnical measures. Overall, the IRTYSH 13 variety is a promising choice for agricultural producers seeking to obtain a stable and high-quality oat yield for both fodder and food purposes.
