Royal Green Perennial Ryegrass
Royal Green was developed by crossing Spreader III from the University of Minnesota with Ragnar II. Spreader III has excellent turf density and lateral growth in mowed turf, while also having improved winter hardiness and reduced steminess. Ragnar II is the second generation of a turf-type perennial ryegrass variety that is distinct from other varieties in its resistance to aryloxyphenoxypropionate (AOPP) herbicide chemistries. Herbicides of AOPP chemistries are effective in the control of annual and perennial grass weeds that are problematic in perennial ryegrass seed production.
