This study was initiated to evaluate the growth characteristics of nine creeping bentgrass(Agrostis palustris Huds.) cultivars in spring. The results are as followings; In the green-up, CY2 was evaluated to the fastest cultivar among tested nine culivars, however, SR1020 was the lastest. CY2 followed by T1 > Penn A4 , Crenshaw, L93 > Penncross > Putter > Dominant > SR1020 in that order. Especially, the green- up of CY2 was begun from beginning of March when was below 5℃. The green-up of CY2 was completed within 65days, it was faster 2 weeks than that of SR1020(80 days) which was the last to green up. In result of the visual quality, CY2 showed the best visual quality the whole Spring. T1 and Crenshaw were also assorted with the high visual quality group whereas SR1020, Dominant and Penncross were included relatively low quality group. Visual quality of bentgrass cultivars was not significantly different from the middle of June. These results are expected to offer useful information for many golf course managers.
