采用ERIC-PCR分析技术,对11株棕色蘑菇栽培菌株亲缘关系进行了分析。结果表明,供试的11株棕色蘑菇菌株具有一定的遗传多样性,在68%的相似水平上把供试菌株分为3个类群,其中菌株011自成一组,与其它菌株具有较远的亲缘关系;菌株009和010相似水平达到95%以上,表明它们具有较近的亲缘关系。 ERIC-PCR analysis was used to analyze the genetic relationship of 11 brown mushroom cultivated strains. The results showed that the 11 brown mushroom strains tested had a certain degree of genetic diversity. The tested strains were divided into three groups at a similar level of 68%, of which strain 011 was self-contained and far away from other strains The similarities of strains 009 and 010 reached more than 95%, indicating that they have a closer genetic relationship.
