Abstract: Zoysia japonica Steud. was first introduced to USA from the northeast part of China in 1895. After that , more than 10 species of Zoysia grasses were introduced from China , Korea and other South-Asia areas.Since 1980ps , the warm-season turfgrasses , particularly Zoysiagrass cultivars , have been increasingly used because of the decline in quality of the cool-season turfgrasses as a result of environmental stresses and diseases in the transition regions between cool and warm climates in USA. Several types of new Zoysia grass cultivars have been selected , bred , and planted in the South and transition regions in USA. On the other hand , China has been importing large quantities of the cool-season turfgrass seeds from USA since 1990's and planted them in almost every city in the country. Many problems with the cool-season turfgrasses have recently surfaced in China. This paper will discuss the valuable lessons that other countries have learned , and will offer suggestions for the development of the domestic industrialization of turfgrasses in China.
