Sugar beet of the Pirat variety is a medium-late, single-stemmed triploid hybrid on a sterile basis, intended for cultivation in the Central, Central Chernozem, and Volga regions of Russia. The root has a conical, slightly oval shape with green above-ground and white below-ground parts. Leaves and petioles are green, leaf arrangement varies from upright to semi-spread, with approximately 70% of leaf mass harvested. Root mass varies by region and averages from 590 to 681 grams. The hybrid is characterized by high yield and sugar content, confirmed by regional data: in the Central region, yield reaches 393 centners per hectare with 18.7% sugar, in the Central Chernozem region — 460 centners per hectare and 15.6% sugar, and in the Volga region — 444 centners per hectare and 17.4% sugar. Sugar content is also high and exceeds average standards, making the variety attractive to the sugar industry.
The Pirat hybrid exhibits good resistance to a range of diseases, including root maggots and cercosporosis, as well as enhanced resistance to root rots. This trait contributes to reduced crop losses and improved root quality. Sugar beet Pirat is widely used in agronomy due to its high technological characteristics and adaptability to various climatic conditions, enabling effective cultivation in diverse regions with different soil-climate conditions.
The crop is warm-loving and heat-tolerant, with an optimal temperature for growth and development of 20-22°C, although photosynthesis proceeds successfully even at temperatures above 40°C. Sugar beet 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 up to 2.5 meters, the plant exhibits good drought resistance. Seeds germinate at temperatures from +4 to +17°C, with emergence time depending on temperature. During the pre-harvest period, the crop can withstand frosts down to -5°C without damage to sugar accumulation, thus expanding its cultivation possibilities in various climatic zones.
