Variety description

10 August 2026

The variety is intended for grazing, haymaking, and silage production. The tetraploid type ensures high productivity in terms of fresh and dry matter yield, as well as an increased sugar content and better feed digestibility compared to diploid varieties.

The variety demonstrates good adaptability and yield in foothill and mountain regions. With proper management, the longevity of the stands can reach 5–6 years. In laboratory studies, the variety showed resistance to glyphosate-based herbicides.
