Description

Although perennial ryegrass provides excellent playability at mowing heights as low as one-half inch on golf course fairways, winter injury is frequently reported. Freezing stress resistance may be influenced by cultivar, mowing height, and fertility. The objectives of this study are to identify perennial ryegrass cultivars suitable for the Northern Plains, as influenced by mowing height and fertility, and to investigate the reliability of a laboratory screening procedure. Following establishment in the fall of 1998, 22 perennial ryegrass cultivars were evaluated in the field during the 1999 growing season for winter injury, genetic color, snow mold injury, rust disease, and turfgrass quality. Additionally, laboratory freezing resistance tests were initiated in December.
