Coverage characteristics were evaluated under main creeping bentgrass (Agrotis stolonifera L.) cultivars used in Korean golf course greens. Eight cultivars of creeping bentgrass (CB) were ‘Penncross’, ‘T-1’, ‘Penn A-1’, ‘Penn A-4’, ‘Shark’, ‘Declaration’, ‘Pure Distinction’ and ‘Pure Select’. Experiment was conducted on a 1m×1m plot with three replication (total plot size=24 m²) of Chunryong country club located in Jincheon, Chungcheongbuk-do, Korea. Weekly coverage rates and required days to 25, 50, 85, and 100% coverage after seeding were measured and analyzed. Significant differences of CB cultivars were observed in weekly coverage rates and required days of the 50, 85, and 100% coverage after seeding. As for the coverage rates, it was 30.0-46.7% (16.7% difference) on 3 weeks after seeding (WAS), 70.080.0% (10% difference) on 4 WAS, 83.3-90.0% (6.7% difference) on 5 WAS and 93.3-100% (6.7% difference) on 6 WAS among CB cultivars, respectively. And the number of days it takes for treated CB cultivars to cover up to 85% of plot was 29.7-35.2 days.
