Variety description

10 August 2026

The variety belongs to the alternative growth type, which allows for both autumn and spring sowing. It possesses high tillering capacity and significant stem growth. Maturity is defined as mid-late, however, the variety is capable of rapid development when moisture is available.

The plant possesses medium to high resistance to rust and powdery mildew infection. The produce is characterized by a high dry matter content and a balanced ratio of fiber and protein, making the variety a valuable forage component.

The variety is intended for green mass production, hay harvesting, or microsilage production. It can be grown both in pure stands and in mixtures with legumes, including vetch, clover, or forage peas. The recommended seeding rate is from 70 to 90 kg per hectare.
