| Abstract/Contents: | "Sequences of the Internal Transcribed Spacer (ITS) regions of the ribosomal DNA locus were evaluated as a tool for identification of fine fescue selections. Sequences were obtained from 44 selections belonging to 11 different species and subspecies, collected from wild populations or old turf sites in North America, Europe, and Asia. Phylogenetic analysis divided the fine fescues into two major clades. These clades corresponded to the division of the fine fescues into the F. rubra and F. ovina aggregates, which is based on morphological characteristics. Within the ovina and rubra aggregates, the maximum number of differences between selections were 18 and 19, respectively. As a result, the phylogenies provided little resolution and bootstrap support values were generally low. Subclades within the ovina aggregate closely corresonded to species, but there was no apparent relationship between subspecies and ITS clades within the rubra aggregate. Based on these results, ITS sequences appear to be a reliable tool for placing fine fescue selctions in the rubra or ovina aggregates. ITS sequences may also be useful for resolving taxonomic issues and identifying species within the ovina aggregate, but not within the rubra aggregate." |
