A simple marker technique called sequence-related amplifi ed polymorphism (SRAP) provides a useful tool for estimation of genetic diversity and phenetic relationships in natural and domesticated populations. Previous studies and our initial screen showed SRAP is highly polymorphic and more informative when compared to AFLP, RAPD and SSR markers. In this study, applicability of the SRAP markers to obtain an overview of genetic diversity and phenetic relationships present among cool-season (C3) and warm-season (C4) turfgrass species and their relationship with other Gramineae species were tested. Phenetic trees based on genetic similarities (UPGMA, N-J) were consistent with known taxonomic relationships. In some cases, well-supported relationships as well as evidence by genetic reticulation could be inferred. There was widespread genetic variation among C3 and C4 turfgrass species. In Dice based cophenetic matrix, genetic similarities among all species studied ranged from 0.08 to 0.94, whereas in Jaccard based cophenetic matrix, genetic similarities ranged from 0.05 to 0.85. C3 and C4 species were clearly distinguishable and a close relationship between italian ryegrass and tall fescue were obtained based on SRAP. Genome structures of turfgrasses are comparable to other Gramineae species. This research indicates that the SRAP markers are useful for estimating genetic relationships in a wide range of turfgrass species. The SRAP markers identifi ed in this study can provide a useful reference for future turfgrass breeding efforts. Grasses are one of the most complex genetic systems in nature, while grass family is defi ned as a single genetic system which evolved ≈55 to 70 million years ago (Kellogg, 2000). Though there have been many years and levels of inves- tigation, the exact composition, organization and evolution of its genome is still unknown. Grass genomes differ tremendously in nuclear DNA content, chromosome number, and repetitive DNA content, but are signifi cantly conserved in both gene content and gene order (Van Deynze et al., 1998). This extensive conservation of gene content order among grass chromosomes has led to the proposal of a progenitor genome structure for all grasses (Bennetzen and Freel- ing, 1993). Turfgrasses constitute a heterogeneous group of species, which differs in reproductive strategy, genome organization and evolutionary history (Caetano-Anolles, 1998). Domestication of turfgrass is recent compared to any other grasses, and is classifi ed into more than 30 spe- cies belonging to 20 genera and 3 subfamilies of Gramineae (Gould and Shaw, 1983). Turfgrass species, dispersed throughout the world, are divided into two major groups: warm-season (C4) and cool-season (C3) species based on their
