Variety description

10 August 2026

The variety is diploid (2x) and belongs to the mid-season group. It is intended for use in forage production, including grazing and haymaking, and is not a decorative lawn variety.

During trials, the variety demonstrated high yield stability. The linear regression coefficient recorded in a number of studies confirms the plant's ability to maintain productivity under unfavorable growing conditions compared to other varieties.
