| 摘 要： | 对采集自云南省元谋等9个县的35个马铃薯和番茄晚疫病菌株用RAPD的方法进行了分子指纹的研究。马铃薯晚疫病菌和番茄晚疫病菌全基因组DNA指纹研究结果表明，两类晚疫病菌有丰富的遗传多态性，在不同的相似水平上可以划分为许多不同的遗传组群。来自不同寄主的菌株间有一定的遗传差异，但马铃薯晚疫病菌和番茄晚疫病菌不能完全划分为两个不同的组群，而是交叉分布在不同的遗传组群中。

| Abstract: | This paper is researched on the molecular fingerprint of 35 isolates of Phytophthora infestans from 9 counties of Yunnan province by RAPD.The results showed the isolates from potato and tomato had abundant genetic diversity.The analysis of clustering indicated all isolates were clustered into different genetic similarity group at different similarity level.It is showed the isolates from potato and tomato had genetic difference.But the isolates from potato and tomato could not clustered into two different genetic group,they could clustered different genetic group. |
