Abstract
Recently, many domestic golf course have showed interest in introducing new cultivars into existing putting greens without reconstruction. But, any report and survey method for interseeding substitute ratio haven't been published. Therefore, this study was conducted to evaluate the effectiveness for interseeding by investigating how many interseeding plants were introduced into existing putting green by using molecular biologic tool. The Woo Jung Hills Country Club was one time introduced penn A4 into penncross putting green. The Lake Side Country Club was three times introduced CY-2 into penncross putting green. The interseeding substitute ratio using SCAR markers was 20% in the Woo Jung Hills Country Club and 35.5% in Lake Side Country Club. The interseeding putting green in Lake Side Country Club was investigated to three site, strong pressure, middle pressure and weak pressure. These substitute ratios were strong pressure 27.1%, middle pressure 37.3%, and weak pressure 47.2%. The data indicated that an interseeding substitute ratio was more increased three times than one time to introducing new cultivar into existing putting green. A long-term program should be made in order to exchange existing cultivar in putting green without reconstruction.
