Cultivation Characteristics and ISSR Genetic Analysis on Seven Pleurotus geesteranus Strains
-
摘要: 对收集的7个秀珍菇菌株栽培特性进行比较,结合ISSR分子标记鉴定,对它们的遗传多样性进行分析,结果表明:农艺性状优良的菌株为P817、P618;供试菌株间遗传相似系数为0.29~0.73,当遗传距离达到0.59水平时供试菌株分成4组,其中P817、P618分属不同组别,存在一定的遗传距离,为秀珍菇的种质资源评价提供理论依据。Abstract: Cultivation characteristic of seven Pleurotus geesteranus strains were comparatively studied,their genetic diversity were analyzed by identifying molecular marker of ISSR.The results showed that strains P817 and P618were excellent in comprehensive agronomic traits and the genetic similarity coefficient for tested strains ranged from0.29 to 0.73.Seven strains were divided into 4groups when genetic distance was at 0.59.The strains P817 and P618were grouped differently by genetic distance.The results provide theoretical reference in genetic assessment for Pleurotus geesteranus.
