Variety description

10 August 2026

The variety was obtained by the induced polyploidy method based on a local breeding population. The tetraploid nature of the variety ensures faster seed germination, increased 1000 kernel weight, higher sugar and moisture content, as well as improved digestibility and disease resistance.

The plant belongs to the group of very early-maturing varieties with heading beginning in April. The variety exhibits high environmental stability and is suitable for use in pastures, hayfields, and as part of mixtures for creating sports and ornamental lawns.
