摘　　要：以采自四川、甘肃、湖南等8省的9份牛角藓标本为材料,运用RAPD技术对牛角藓的分类修订进行研究.利用15条随机引物共获得134条清晰谱带,其中多态性条带占91.79%,牛角藓各标本间的遗传相似系数为0.703～0.870.结果显示:虽然9份牛角藓标本的形态特征差异非常大,但通过RAPD分析表明其为同一种.Choosing nine Cratoneuron filicinum specimens collected from Sichuan, Gansu, Hunan, Yunnan, Liaoning, Hebei, Jilin and Xinjiang as the materials, the paper researched on the taxonomic revision of different C. filicinum by RAPD, obtained 134 distinct bands from 15 primers, of which 91.79% were polymorphic, and the genetic similarity coefficient （GS） among nine C. filicinum specimens varied from 0. 703 to 0. 870. The results showed that the individuals of nine specimens are the same specie though they are very different in morphological characteristics.
