| 摘 要： | 采用RFLP技术 ,对中日美 3国的 2 6个子群体共 75 7个栗疫病菌菌株的核DNA进行了群体遗传结构分析。结果表明 ,栗疫病菌的中国子群体间遗传结构有明显的分化 ,日本子群体间的遗传结构差异不明显 ;在美国和亚洲的栗疫病菌群体间没有发现基因流的迹象 ;美国栗疫病菌群体的遗传结构与日本群体的关系比较密切 ,而与中国群体间的差异较大。

| Abstract: | The genetic structures of chestnut blight fungus, Cryphonectria parasitica, among 26 subpopulations including 757 isolates, from populations of China, Japan and the USA, were analysed with DNA RFLP. The results showed that the subpopulations from China were significantly subdivided while those from Japan were not. There is currently no gene flow between populations of Asia and of the USA; both population structures of the USA and Japan were related more closely than those of Japan to China. |
