Ardan is a single-seed diploid hybrid sugar beet (Beta vulgaris L. ssp. vulgaris var. saccharifera Alef.) on a sterile basis, intended for cultivation in various regions, including the Central Chernozem, North Caucasus, Ural, and Almaty areas. The root has a conical shape, facilitating harvest, and the leaves are semi-erect and green, making up about 40% of the plant's total mass. The hybrid is characterized by high yield — up to 95 tons per hectare, with sucrose content varying from 16.8% to 21%, ensuring a high sugar yield — up to 87 centners per hectare. Ardan responds well to fertilizers and exhibits resistance to pests and diseases, including moderate resistance to root rots. Sugar beet Ardan is characterized by heat tolerance and heat resistance. The optimal temperature for growth and development is 20-22°C, but photosynthesis occurs effectively even at temperatures above 40°C. Seeds germinate over a wide temperature range from +4 to +17°C, with emergence time depending on temperature and varying from 10 to 15 days. The plant requires adequate moisture, especially during the intensive root growth period in July-August. Due to its well-developed root system, capable of absorbing water from depths of about 2.5 meters, the hybrid tolerates drought well. Ardan can withstand frosts down to -5°C during the pre-harvest period without damage to sugar accumulation, although lower temperatures may negatively affect this process. This hybrid is suitable for cultivation in various climatic conditions, ensuring a stable and high yield of sugar beet with good technological characteristics of the roots.
