Abstract/Contents:"Bermudagrass (Cynodon spp.), a forage and turf crop, is a commonly used perennial grass in the United States, Australia, Africa, India, and South America. It is known for its high drought tolerance, its ability to grow in a variety of soils, and its rapid recovery rate from wear and compaction. The USDA germplasm set is composed of plant introductions (PI's) collected around the world and comprises a number of different Cynodon species, primarily C. dactylon. In number, the entire population represent 137 PI's from the NPGS maintained at Griffin, GA, and 146 PI's from the forage bermudagrass core collection maintained at Tifton, GA. The goal of this research was to determine ploidy level and genome size for the complete USDA bermudagrass collection. The collection was planted at the Plant Science Research and Education Unit, Citra, FL. For chromosome counts using cytological staining techniques, roots and meristems were collected from a set of PI's with known ploidy and they represent different Cynodon species. The PI's with determined chromosome counts were used as internal standards to run flow cytometry in the PI's that do not have published ploidy levels. By providing information on the chromosome number and ploidy levels, this research will help support current efforts to perform genetic studies using this germaplasm, such as correlations among phenotypic traits with ploidy level to use in future selections for breeding improved forage and turf cultivars."
