This disclosure provides perennial ryegrass plants having determinate-stolons developed by subjecting large number of perennial ryegrass plants to intense traffic. This grass can quickly repair (high regeneration potential) itself from traffic damage, and has good turf qualities compared to other perennial ryegrasses. The high regeneration potential gives it the ability to quickly repair itself from traffic damage and fill in open areas in turf. Methods of using the perennial ryegrass grass plants and seed are also provided. This grass is suitable for use in turf, for example turf that is exposed to significant traffic. This disclosure also provides methods of selecting for such grass plants.
