Carpetgrass (Axonopus fissifolius Raddi) is a warm-season perennial grass species indigenous to Central and South America and the West Indies. It is used sparingly as a forage and turfgrass in the southeastern United States. Because of its low maintenance attributes, carpetgrass may have potential for development as an alternative turfgrass species for use in lower latitudes. There is limited information regarding the types and amounts of variation that exists for this species. Research objectives were to make a collection of carpetgrass germplasm, determine the variation within the collection for morphological and turfgrass performance characteristics and to calculate estimates of heritability. The germplasm collection consists of genotypes obtained from commercial seed and collection trips. The collection is therefore divided into two sources, the seeded material and the collected material. Experiments were performed in both greenhouse and field conditions. In both environments, treatments (genotypes) were arranged in a randomized complete block design with three replications. The greenhouse study evaluated morphological traits and the field study evaluated turfgrass performance characteristics. Differences in means were found to exist between genotypes for most traits. Differences in means and variances were found to exist between the two sources for some traits. Heritability estimates for most traits were moderate to high, indicating the potential to alter these traits through conventional breeding.
