| 摘 要： | 利用致病性测定及Pot2-rep-PCR技术对2007、2008年采集自江苏省五大稻区的稻瘟病菌株进行多样性分析,这2年的菌株被划分为10个小种和14个系谱,其中ZG1为优势小种,JSL5为优势系谱,研究结果表明:江苏稻瘟病菌具有丰富的多样性,但与1999 - 2002年的群体结构比较时发现,群体结构趋于简单；对病原菌...

| Abstract: | Pathogenicity determination and Pot2rep-PCR techniques were used to analyze the diversity of Magnaporthe.grisea from Jiangsu in 2007 and 2008,respectively.They were divided into 10 Physiological race and 14 lineages,in which ZG1 and JSL5 are dominant.The results showed that the rice blast fungus are rich in diversity in Jiangsu,but when compared with the group structure of 1999-2002,it tends to be more simple;By analyzing temporal and spatial distribution of M.grisea,we found that Population structure of M.... |
