Abstract/Contents:"Sixty-three cultivars and experimental selections were estanlished in Sep 1986 at the Joseph Valentine Turfgrass Research Center, University Park, PA. The treatments consisted of entries in the 1986 National Penennial Ryegrass Test. The plots were 1.2 x 1.8 m and seeded at a rate of 2.5 kg per 100 m2. All treatments were replicated three times in a randomized complete block design. The turf was mowed at 2.9 cm and treated with a combination of 2, 4-D/MCPP/dicamba to control broadleaf weeds. The test was fertilized with 0.5 kg N per 100m2 in April 1989, and received no fungicide or insecticide applications. The test site was irrigated when necessary to prevent drought stress. A uniform infestation of red thread disease occurred in May 1989 and the plots were visually rated for disease injury on 22 May. Significant differences were found in the resistance of perennial ryegrasses to red thread, indicating a potential to improve resistance through selective breeding. `Rival' and `Delray' showed the least amount of disease injury, while `Barry', `SR 4031' and `PST-2PM' were severely injured."
