| 摘 要： | 研究内蒙古西部马铃薯主产区马铃薯晚疫病菌的交配型组成及对3种常用杀菌剂的敏感性,为生产上防治马铃薯晚疫病提供依据.2008年从内蒙古西部马铃薯主产区分离94个马铃薯晚疫病菌株中,测定其交配型,结果表明,82株为A1交配型,占被测菌株的87.2％；8株为A2交配型,占被测菌株的8.5％；4株为A1A2交配型,占被测菌株的...

| Abstract: | The isolates of Phytophthora infestans were collected from the west of Inner Mongolia in 2008.The mating type and response of the isolates to three chemicals were then determined.Among 94 isolates tested,82 isolates belonged to A1 mating type,accounting for 87.2%;8 was A2 mating type,accounting for 8.5%;4 was A1A2 mating type,accounting for 4.3%;13 was self-fertil mating type,accounting for 13.8%.Seven strains of A2 mating type were detected in Hohhot area and only one was detected in wulanchabu,This result... |
