Perennial ryegrass (Lolium perenne) is a turfgrass species that is quick to germinate and establish but is one of the least winter hardy cool-season species. As part of the WinterTurf project, we are trying to understand the physiologic characteristics that contribute to freeze tolerance.

Field evaluation of perennial ryegrass accessions

Summary of study

Plants of 300 wild and landrace accessions from the National Plant Germplasm System (NPGS) and a collection at Rutgers University were tested in two field environments for winterhardiness (as measured by tiller survival) and other turf traits. The field environments were at Becker and St. Paul, MN. The traits measured were seedling vigor, tiller survival in 2005 and 2006, spring growth in 2005 and 2006, summer and autumn turf quality, color, leaf texture, crown rust incidence, growth habit and spreading vigor.
