PRIMORSKAYA 81 — a soybean variety (Glycine max (L.) Merr.), belonging to the Manchurian subspecies, characterized by a semi-determinate type and early maturity with a vegetation period of 100-110 days. This variety is distinguished by high drought resistance and is suitable for cultivation in the Far East regions, including Primorsky Krai, Amur Oblast, and Khabarovsk Krai. The mass of 1000 seeds varies from 170 to 198 grams, indicating the large-seededness of the variety. The productivity potential reaches 38.4 centners per hectare, while the average yield in the Far East region is about 16 centners per hectare, and the maximum is 29.3 centners.
Seeds of the PRIMORSKAYA 81 variety contain a high level of protein — from 38.8 to 41.1%, as well as a significant amount of fat — about 21.7-22.8%. Due to such composition, this variety is widely used in the food industry for the production of tofu, soy milk, and other products. Soy protein is rich in essential amino acids, including lysine, which enhances its nutritional value. Moreover, soy is an important oil crop, making it in demand both in the food and industrial sectors.
PRIMORSKAYA 81 — a sun-loving and heat-demanding short-day plant, which must be taken into account when choosing growing conditions. Soy also plays an important role in crop rotation, acting as a valuable predecessor for plough and cereal crops due to its nitrogen-fixing ability, which improves soil fertility. Thus, this variety combines high productivity, quality seed composition, and adaptation to the climatic conditions of the Far East.
