GYESER is a medium-maturing spring oat (Avena sativa L.) variety characterized by high agronomic indicators and adaptability to various climatic conditions. The plants are tall, with a bush height of about 100 cm, semi-erect, with a medium-length two-sided ear and horizontal branch placement. Ears are drooping, covered with short glume scales with a strong waxy coating, which contributes to resistance to shattering. The mass of 1000 grains varies from 30 to 42 grams, indicating the variety's large-grained nature. Grain density is 440-490 g/l, which is a good quality indicator.
The variety is distinguished by high yield, which in various regions reaches from 37.6 to 57.9 centners per hectare, making it attractive for agricultural production. The vegetation period ranges from 78 to 91 days, allowing the variety to be used in the East-Siberian and Far Eastern regions. GYESER is resistant to lodging, which facilitates harvesting and reduces yield losses. Moreover, the variety exhibits drought resistance, increasing its reliability under unfavorable weather conditions.
However, the variety is susceptible to certain diseases, such as common bunt, bacterial blight, and crown rust, and has low drought resistance under some conditions. Despite this, the variety is recommended for cultivation in the East-Siberian region and has shown high yield in Buryatia and the Primorsky Krai. GYESER is a variety of brunnea and differs in the absence or very weak tendency for awniness in the first grain, which improves grain quality and its suitability for further use.
