摘要： Although Stylosanthes gracilis was the first stylo to be introduced as a green manure cover crop for young rubber plantations in 1961, the S. guianensis cultivars Cook and Graham introduced in the 1970s and 1980s were largely responsible for the stylorevolution in China. Before serious anthracnose outbreaks, these cultivars covered over 13,000 ha in southern China. Anthracnose had shifted emphasis to S. guianensis CIAT184 and successful cultivars originate from this introduction (Guodao et al., 2004) Well-adapted varieties are now available for much of southern China and in 2003, the total area of stylo exceeded 200,000 ha, Stylo development has been greatly aided by the release of commercial cultivars. Initially these were from Australia, but morerecent cultivars have been selected from introduced accessions, Reyan No 2, Reyan No 5 Reyan No 7 and Reyan No 1.3 are selections from CIAT 184; Reyan No 10 originated from CIAT 128.3 and cultivar 907 was developed through Cr~(64)-gamma radiation technology. These are suitable for utilisation for leaf meal production, pasture improvement, green manure and soil conservation and the variety Reyan No.5 is cold-tolerant.
