MS S 1660 is a high-sugar diploid hybrid of sugar beet of the NZ type, intended for cultivation in various climatic zones, including Polesye, Forest-Steppe, and Steppe. The plant is characterized by a semi-prostrate leaf rosette, with 50 to 60 leaves forming on a single plant, which promotes active photosynthesis and good crop development. The root system is taproot, penetrating deep into the soil up to 2-2.5 meters and branching laterally up to 1-1.2 meters, ensuring reliable nutrition and resistance to adverse conditions. The hybrid root has a cylindrical-conical shape, differs in large dimensions, and is fully buried in the soil, which facilitates harvest collection and reduces losses. MS S 1660 exhibits high resistance to major sugar beet diseases, such as Cercospora, powdery mildew, and root rot, which significantly enhances crop reliability and quality. The sugar content of the roots reaches 18-19%, making this hybrid attractive for industrial sugar production. The MS S 1660 hybrid is adapted for use with the herbicide Roundup, which allows effective weed control and increased yield. Thanks to its morphological and biological features, this hybrid ensures a stable and high yield of sugar beet, making it a profitable choice for agrarians seeking high-quality and economically efficient production.
