Variety description

10 August 2026

The variety is a tetraploid type of ryegrass used as a short-term forage crop. It is intended for winter forage production, livestock grazing, as well as hay and silage harvesting.

The plant is characterized by rapid growth in the winter period and high nutritional value in the spring. The variety is ready for grazing 45–70 days after sowing. In breeding, increased resistance to rust was achieved; the variety is suitable for frequent grazing.
