Variety description

10 August 2026

The variety is diploid and focused on forage use for creating a green conveyor, allowing for a harvest in the year of sowing. It possesses the ability for rapid development of green mass, while the mown grass is easier to dry for hay compared to tetraploid varieties of this species.

In the past, the variety was represented in European recommended lists, however, it is currently excluded from them due to the emergence of new breeding achievements with higher productivity indicators.
