Leymus chinensis 'RIDU' is a hybrid barley grain variety developed within the agricultural productivity enhancement program. The variety is characterized by high yields of up to 8–9 t/ha and resistance to major diseases, such as leaf blight (Pythium) and powdery mildew (Puccinia), as well as pests – aphids and mites. Thanks to these characteristics, 'RIDU' is suitable for commercial grain production in temperate climatic zones.
Key agronomic parameters include high grain density with protein content of 12–13% and starch of 70–75%. Growth duration is 90–100 days, plant height – 80–95 cm. Seeds are light green in color with a characteristic 'speckled' pattern. Resistance to drought and cold allows the variety to be used in various climatic conditions.
At sowing on areas from 0.5 to 1 m²/seed under optimal agronomic conditions, a yield of 8–9 t/ha is achieved. To minimize the risk of leaf blight, proper fertilization and mulching are recommended, and for fighting powdery mildew – the use of fungicides. Protection against aphids and mites is possible with the use of insecticides. Overall, Leymus 'RIDU' represents a reliable agronomic product, ensuring stable yields and resistance to adverse factors.
