Abstract/Contents:"The development of 'Tifgreen' bermudagrass, and the subsequent mutations of this cultivar, has revolutionized the game of golf in the southern United States as superintendents now have access to a high-quality putting surface capable of withstanding hot summers. However, due to the nature of mutations, the genetic makeup of these grasses on the market has not changed much throughout the years. The lack of diversity may make them vulnerable to various natural pests that can impact playability and freeze temperatures that inflict winterkill. In recent years, Oklahoma State University and other universities have begun to create new hybrids between Common (Cynodon dactylon) and African bermudagrasses (C. transvaalensis) that are able to withstand putting green mowing heights while increasing the genetic diversity within this class of bermudagrass. To quantify this diversity, simple sequence repeats (SSRs) were used to assess the genetic relationship and variation among 14 experimental hybrids against two standards 'TifEagle' and 'Tifdwarf'. In total, 54 SSR primer pairs spread across all 18 linkage groups of common bermudagrass amplified 311 polymorphic bands. The genetic similarity coefficient ranged from 0.53 to 1 among the 16 entries. The highest level of diversity occurred between the three ultradwarfs and all other entries in the trial, with the ultradwarfs having a similarity coefficient of 1 among themselves. This data shows there is little variation within the ultradwarf cultivars, but significant variation is being introduced through traditional breeding methods. Continued work is being done to evaluate the morphological characteristics of these experimental hybrids, as well as their performance under golf course settings."
