摘　　要：以菌丝培养特性和ISSR分子标记对采自不同国家和地区的21株桦褐孔菌菌株进行了遗传多样性分析,并对2种方法的聚类结果进行了比较分析。结果表明,菌丝培养特性标记的聚类结果与ISSR分子标记聚类结果基本一致,均与地理分布有较强的相关性,但ISSR分子标记结果与纬度相关性较大,菌丝培养特性标记的聚类结果与生态环境相关性较大。因此,建议在桦褐孔菌的遗传多样性分析和种质鉴定中采用分子标记,并辅之以其他标记的研究方法。Culture characteristics of mycelium and ISSR markers were used to analysis the genetic diversity of 21 Inonotus obliquus strains from different countries and regions, and the cluster result of the two meth- ods were compared. The results showed that the cluster results of the mycelium culture characteristics and ISSR markers are basically the same, but the results of ISSR makers showed a close relationship with lati- tudes, while biological characteristics relate to ecotype strongly. Therefore, it is suggested that molecular markers added with other markers should be used in the study of genetic diversity and germplam identifica- tion of Inonotus obliquus.
