简介：利用33对SSR引物对来自中国16个省的46份野生芒（Miscanthussinensis）种质进行遗传多样性分析。结果显示：（1）33对SSR引物共扩增出87条DNA条带，75条为多态性条带，占86．21％，条带大小范围80～310bp；（2）遗传多样性参数分析结果：Shannon’s信息指数（1）变幅为0．020—1．522，平均为0．745，引物多态性信息含量（P1C）变幅为0．040～0．738，平均为0．445，遗传相似系数（GS）的变幅为O．315～0．933，平均为0．569，说明我国芒种质资源遗传基础宽，遗传多样性丰富；（3）相似系数UMPGA聚类结果与主成分分析（PCA）结果一致，可将46份种质分为3大类群，类群I主要由中部芒组成，类群Ⅱ主要由北方芒组成，类群Ⅲ主要由南方芒组成，西南芒在每个类群中均有渗透，这一结果说明芒种质资源的遗传分化与其种源的地理分布有一定的相关性，但与地理起源不能完全吻合。
