Abstract/Contents:"Several new bentgrasses have been released for use on golf course putting greens in the last 3-5 years. Generally the introduction of these grasses to a golf course would require extensive greens renovation or new construction. Considering the 14,000 golf course[s] in the United States alone, most of which will not undergo renovation or major reconstruction, and many of which could take advantage of these new grasses if their introduction and conversion did not require extensive renovation. When bentgrass putting greens are interseeded with new cultivars, it is desired to have a quick transition with minimal interruption of play. Studies of physical and chemical practices have been conducted for this purpose; however, there is no simple method to measure the population shifts. To facilitate this area of study as well as to provide the scientific evidence of cultivar transition, we propose the use of an electrophoretic technique to identify genetic or population shifts in the turfed area. Isoenzyme banding patterns of bulk leaf samples from an interseeded green were compared with those of proportional blends of two cultivars. The green's composition was estimated based on isoenzyme phenotype pattern which most closely approximately the proportionate blend of the two cultivars. Electrophoresis can be used as a simple technique for measuring population shifts of interseeded or initially blended greens."
