Variety description

10 August 2026

The variety is tetraploid (4n) and belongs to the late heading group; the heading date occurs in early June. Unlike most tetraploids, it possesses a high turf density characteristic of diploid forms.

It is characterized by good growth during the summer period, longevity, and high resistance. The variety possesses high dry matter digestibility and exceptional palatability, ensuring low grass residues after livestock grazing.

Specialized for grazing use and is used as a component in grass mixtures for regions with intensive dairy and beef cattle farming.
