Abstract/Contents:"As a crop of major economic and aesthetic value, turfgrasses like bermudagrass (Cynodon spp.) have lagged in their entry into the genomics-based era, stemming from the lack of available resources. Genomic tools and DNA markers are being developed to aid in bermudagrass improvement, but at this stage they are difficult to incorporate into current breeding strategies and would benefit from solid knowledge of certain characteristics, such as species classification and ploidy data. In a previous study we used DNA markers to assess the genetic diversity within the genus Cynodon and discovered unexpected species groupings. Various accessions of five of the six species tested did not group by the botanical species classification with accessions from up to three different species forming closely related groups, and with different accessions from the same species present in different DNA-based groups. This suggests that the current systematics of the genus is incorrect. Additionally, triploids, presumably representing spontaneous interploidy hybrids, were frequent. The focus of this study is now to explore the population structure and genetic diversity of select accessions available from public germplasm repositories using genetic markers and ploidy information. Ploidy levels vary among Cynodon species, and further understanding these accession groupings and/ or species classifications in relation to ploidy data would not only allow for breeding efforts to leverage identified genetic markers, but to also correctly classify and eliminate redundancies in core collections, such as sterile interspecific hybrids or accessions with high levels of genetic similarity."
