Seed weight less than APM, having a shorter seed length and thinner seed width. Entered in the 1999 National Turfgrass Evaluation Program's perennial ryegrass test where demonstrated good establishment, spring and summer density, and spring, summer, and fall living ground cover. In these trials, displayed moderate to good resistance to pink snow mold (Microdochium nivale), red thread (Laetisaria fuciformis), large brown patch (Rhizoctonia solani), typhula blight (Typhula incarnata), and melting out (Drechslera spp.). Maintained favorable living ground cover after traffic treatments in Missouri. Developed for year-round use on lawns, fairways and roughs, industrial sites, and parks. Turf-type perennial ryegrass with medium-dark green color, medium-fine texture, medium density, and an upright growth habit at initial anthesis. | 1650225 | PI 634337 |

Can be differentiated by the heavier weight seed of Goalkeeper. In Post Falls, ID, heading date averages June 3 to 5, plant height to inflorescence tip averages 60.4 to 62.6 cm, and flag leaf width at 1 cm from the collar averages 4.08 to 4.34 mm. In turf trials, genetic color is medium-dark, improved over earlier releases such as Advent or APM. Good turf quality performance with improvements over Advent, APM, Manhattan II, and Imagine. Plant density medium-high, medium-fine leaf texture, and moderate resistance to pink snow mold (Microdochium nivale), gray leaf spot (Pyricularia grisea), and large brown patch (Rhizoctonia solani) diseases. Developed for year-round turf use on lawns, golf course fairways, industrial sites, and parks in areas where perennial ryegrass is adapted for turf. Acceptable performance in company trials in ID, MD, OH, and CA. Has shown good turf quality in winter overseeding trials with College of the Desert, CA and is also recommended for overseeding of dormant warm-season grasses. | 1649987 | PI 634204 |
