摘　　要：综合国内外体细胞无性系变异的相关研究,概述了体细胞无性系变异产生方法、变异机制以及变异频率,详细地介绍了体细胞无性系变异在选育抗病虫害、逆境胁迫以及具优良农艺性状草坪草品种上的应用,讨论了应用体细胞无性系变异育种存在的问题及前景。On the basis of studies relevant to somaclonal variation in China and abroad, the variation inducing methods, variation mechanism and frequency were reviewed. The application of somaclonal variation on breeding or selection of new turfgrass varieties with pest-resistance, stress tolerance, or other elite agricultural characteristics was reviewed in detail. The existing problems and prospects of somaclonal variation breeding were also discussed.
