Variety description

10 August 2026

The variety is a tetraploid Italian ryegrass that can be classified as Italian or Westerwold type. The plant is characterized by a bunch-type growth habit and adaptability to various soil types, including loamy and sandy-loam soils, as well as the ability to tolerate short-term flooding for up to seven days.

The variety is intended for pasture establishment, hay harvesting, silage production, and green fodder production in mixtures for livestock. To maintain productivity, it is recommended not to mow the plant below 7.6 cm, and for maximum biomass yield, to apply nitrogen fertilizers after each utilization cycle.
