| 摘 要： | 采用rep-PCR技术对福建省189个稻瘟病菌菌株进行DNA指纹图谱分析.结果表明:在58%相似水平上可以将供试菌株分为15个遗传谱系,表明该菌具有丰富的多态性.其中谱系FJL04出现频率为35.98%,为优势谱系.利用全国统一生理小种鉴别体系和LTH-NILs鉴别体系从供试的189个稻瘟病菌株中分别鉴别出15和21个致病型(生理小种),优势型分别为ZB13和J76.2,出现频率分别为58.72%和28.57%.采用这2套鉴别体系鉴别的致病型与DNA指纹图谱之间无明显的对应关系. |

| Abstract: | The DNA fingerprints of 189 isolates of Magnaporthe grisea from Fujian were constructed using rep-PCR technique.All isolates could be divided into 15 genetic lineages at 58% similarity level.Among the 15 genetic lineages,FJL04 that consisted of 68 isolates was recognized as dominant lineages with occurrence frequency of 35.98%.The 189 isolates could be respectively classified into 15 and 21 pathotypes by Chinese race differentials and LTH-NILs,and their dominance types were ZB13 and J76.2 with occurrence fr... |
