Variety description

10 August 2026

The hybrid is intended for use in conditions requiring protection against soil-borne pests. The variety possesses pronounced resistance to beet cyst nematode (Heterodera schachtii), which contributes to a reduction in the pest population in the soil during cultivation.

The economic feasibility of using the hybrid is highest in fields with a nematode population density exceeding 1000 eggs and larvae per 100 cm³ of soil. During the testing period, the variety demonstrated yield and quality indicators comparable to other hybrids resistant to nematodes and Rhizoctonia.
