| Abstract/Contents: | "North Shore Country Club, Glenview, Illinois, located in the northern suburbs of Chicago, was one of the sites selected to evaluate creeping bentgrasses in an on-site cultivar evaluation study jointly funded by the United States golf Association (USGA), the Golf Course Superintendents Association of America (GCSAA), and the National Turfgrass Evaluation Program (NTEP). Besides quality ratings, the trial at North Shore C. C. also collected data on differences in the rate at which annual bluegrass invaded creeping bentgrass cultivars. Among the study's findings: All of the cultivars had a five-year mean performance greater than 5, the minimally acceptable putting green quality rating. Five cultivars stood out in this study,` Penn A-1', `Penn A-4', `Penn G-1', and `Penn G-6', and `L-93'. They were uniquely fine textured with extremely high density, and all produced outstanding putting surfaces. There were significant differences among the cultivars in their ability to restrict Poa annua invasion. The top statistical group of bentgrasses had a range of 3.5% to 7.5% Poa coverage compared to over 20% Poa coverage in the 'Penncross' plots. Differences in Poa invasion may be due to cultivar differences in plant densities, growth habit, differences in growth flushes, and aggressiveness allowing more aggressive types to fill cultivation holes, ball marks, and other damage before the Poa has a chance to become established." |
