【摘要】Lentinula edodes is an important cultivated mushroom in China, and accurate and reliable identification of individual cultivars is a prerequisite for successful cultivation and variety protection.In this study,the whole genome sequence of L.edodes was used to generate 200 simple sequence repeat (SSR) markers for delineating 25 commercial cultivars and for determining their genetic diversity.Our data revealed a relatively high level of genetic similarity among the cultivars,with average,minimum and maximum genetic similarity coefficient values of 0.776,0.567 and 1.000,respectively.Seven SSR primer pairs delineated eleven of the cultivars (Cr-02,Minfeng-1,Xianggu 241-4,Senyuan-1,Senyuan-8404,Xiang-9,Guangxiang-51,Huaxiang-5,L952,L9319 and L808)based on their unique multilocus SSR fingerprint profiles.
