Abstract/Contents:"Zoysiagrass (Zoysia spp.), a warm-season turfgrass, that provides an excellent sod-forming turf surface, especially golf course fairways in the transitional and warm climatic regions of the United States. Depending the species of zoysiagrass, cold hardiness (i.e., winter injury and freeze tolerance) can be both a strength and shortcoming. One the most cold hardy (or winter-hardy) zoysiagrass cultivars is 'Meyer' zoysiagrass (Z. japonica), which is also been the most widely used cultivar of choice since its release in 1951. Breeding efforts in the last decade have selected ten experimental hybrids that have exhibited comparable/superior cold tolerance to Meyer, but finer texture, and improved large patch tolerance in the field. However, further research is required to quantify freeze tolerance of 10 zoysiagrass genotypes compared to commercial cultivars in a cold stress simulator. Freeze tolerance (LT50, lethal temperature killing 50% of the plants) ranged from -9.8 °C (Diamond) to -14.1 °C (DALZ 1812). Results indicate there are multiple experimental zoysiagrass hybrids that have similar freeze tolerance compared to Meyer, which had a LT50 of -12.7 °C. Thus, these experimental genotypes may be well adapted to northern areas of the transition zone."
