IRTYSH 22 is a medium-late variety of spring oats (Avena sativa L.) intended for the production of green fodder and grain silage. The plant is tall with a semi-erect bush, a two-sided awn with semi-erect branch arrangement, and drooping spikelets. The grain is large, hulled, with a 1000-grain weight averaging 38-44 g. Leaf sheaths, leaf margins, and the upper stem node are glabrous. The variety is distinguished by its lodging resistance due to a larger stem diameter in the lower part and high resistance to powdery bunt, ensuring harvest reliability.
The green mass yield of the IRTYSH 22 variety is high, averaging 36.9 t/ha, exceeding standard indicators by 5.4 t/ha. Dry matter content reaches 35.3 c/ha. The grain contains approximately 9.9-13.7% protein, 3.57% fat, and 42.6% starch, while the grain hulling percentage is 27.2%. Fiber content reaches 33.4%. The variety exhibits good drought resistance and lodging resistance, confirmed by ratings of 4 and 5 points respectively.
IRTYSH 22 is recommended for cultivation in various regions, including the Ural, West Siberian, North Kazakhstan, and Kostanay regions, as well as the Omsk and Tomsk regions. Thanks to its high productive qualities and disease resistance, this oat variety is a reliable choice for producing high-quality green fodder and grain, making it in demand among agricultural producers.
