摘　　要：SSR分子标记是近年来普遍应用的分子标记之一。大型真菌中常用的SSR分子标记开发策略有三类,包括传统基因文库筛选法、富集文库筛选法和数据库筛选法,其中富集文库筛选法因其分离效率高而被采用较多。本文综述大型真菌中SSR分子标记的应用现状,发现相关研究多数集中于种系鉴定和遗传多样性分析,有关遗传图谱构建和辅助育种虽有涉及但研究较少。讨论了SSR分子标记在大型真菌研究中存在的问题与发展前景。The SSR （simple sequence repeats） marker has become one of the most popular molecular markers recently. There are three strategies to develop SSR marker in macrofungi, traditional library method, enriched library method and GenBank screening. Among them, en- riched library method has been used more frequently due to its higher efficiency. The applications of SSR marker in macrofungi are reviewed, with the conclusion that genetic identifica- tion and genetic diversity analysis are studied commonly while the genetic map construction and assistant breeding are still to be improved. In addition, the existing problems and devel- oping prospects of SSR marker in macrofungi are discussed.
