DANIK is a variety of oilseed flax (Linum usitatissimum L. var. intermedia) that is characterized by medium maturity, high shattering resistance, and disease resistance. The plants are of medium height, around 68-75 cm, with a blue-violet corolla color in the bud stage and light blue when fully developed. The seeds are dark brown, with an average mass of 7.3-8.0 g per 1000 seeds, and a high oil content ranging from 48.0% to 51%. The capsule is of medium size, and the stigma at the base is white. The variety is characterized by synchronized flowering and maturation, which promotes uniform crop formation. DANIK is adapted for cultivation in various regions of Russia, including the Central Black Earth, North Caucasus, Ural, and West Siberia regions. It demonstrates high resistance to lodging and drought, making it a reliable choice for farmers in these areas. The potential yield of the variety reaches 2.5-2.7 tons per hectare, while the average seed yield in the region is about 16.2 centners per hectare, with maximum indicators up to 27 centners per hectare. The high oil content and sufficient plant height allow DANIK to be used as a dual-purpose variety—for oil and fiber production. Thus, the DANIK variety represents an effective and versatile solution for oilseed flax production, combining high productivity, drought resistance, and quality seed characteristics. Its application contributes to the production of valuable products, such as oil and fiber, which expands the possibilities for using the crop in agriculture.
