* Cultivars within their types showed high genetic similarities (Curley, J. and G. Jung. 2004. RAPD-based genetic relationships in Kentucky bluegrass: comparison of cultivars, interspecific hybrids, and plant introductions. Crop Science 44: 1299-1306). Genetic clustering was highest in Midnight > BVMG > America.
