| Abstract/Contents: | "Stenotaphrum secundatum (Walter) Kuntze, known as "St Augustinegrass" in the USA and "buffalo grass" in Australia, is a widely used turfgrass species in subtropical and warm temperate regions of the world. Throughout its range, S. secundatum encompasses a great deal of genetic diversity, which can be exploited in future breeding programs. To understand better the range of genetic variation in Australia, morphological-agronomic classification and DNA profiling were used to characterize and group 17 commercial cultivars and 18 naturalized genotypes collected from across Australia. Historically, there have been two main sources of S. secundatum in Australia: one a reputedly sterile triploid race (the so-called Cape deme) from South Africa now represented by the Australian Common group naturalized in all Australian states; and the other a "normal" fertile diploid race naturalized north from Sydney along the NSW coast, which is referred to here as the Australian Commercial group because it has been the source of most of the new cultivars recently developed in Australia. Over the past 30 years, some US cultivars have also been introduced and commercialized; these are again "normal" fertile diploids, but from a group distinctly different from the Australian Commercial genotypes as shown by both DNA analysis and grouping based on 28 morphological-agronomic characteristics. The implications for future breeding within S. secundatum in Australia are discussed." |
