Lolium perenne

Perennial ryegrass

All that a Perennial Ryegrass needs...

Combines rust resistance and high yield
KETARION 1 is a late diploid with high first cut and a high tolerance to rust. The charts below confirm the high level of disease tolerance, dense sward and good cold resistance.

Late heading but still high yielding
The combination of a total high dry matter yield, with a particular very high yield of the first cut and excellent rust resistance, KETARION 1 is the basic for optimal forage supply in quality and quantity.


  • Diploid and late heading
  • Persistent
  • Dense sward
  • Excellent rust tolerance
