SR 74 F is a single-seed diploid hybrid of sugar beet (Beta vulgaris L. ssp. vulgaris var. saccharifera Alef.) on a sterile N-type base. This mid-season hybrid is characterized by high yield and good sugar content, making it in demand for agronomic cultivation in various regions. The plant type is yield-sugar, ensuring an optimal combination of root mass and product quality.
The hybrid is recommended for cultivation in the Central-Black Earth, North-Caucasus, and Middle-Volga regions. In the Central-Black Earth region, the average root yield reaches about 421-464 centners per hectare with sugar content of 18.1-18.2%, ensuring sugar collection of up to 74-83 centners per hectare. In the North-Caucasus region, root yield is approximately 466 centners per hectare, while sugar content is slightly lower—at about 17.2%—but sugar collection reaches 84 centners per hectare. The average root mass is 555 grams.
SR 74 F has moderate resistance to root eelworm but is susceptible to powdery mildew and Cercospora leaf spot, requiring attention to plant protection during the growing season. Thanks to its characteristics, the hybrid is suitable for producing high-quality raw materials for the sugar industry, ensuring stable yield and sugar content indicators with proper agronomic approach.
