摘要
由致病疫霉Phytophthora infestans(Mont.)de Bary引起的晚疫病是目前危害马铃薯生产最严重的病害之一,明确A2交配型在黑龙江省的存在与否,对晚疫病防治策略的制订具有重要的指导意义。本研究将采自黑龙江省大兴安岭、嫩江、讷河、克山、海伦、绥棱、绥化、巴彦、呼兰、哈尔滨、双城、林口、望奎的马铃薯晚疫病样品进行分离纯化得到124个菌株,通过对峙培养鉴定方法进行交配型测定,结果显示:124个菌株中未发现A2交配型菌株,表明黑龙江省未出现马铃薯晚疫病A2交配型。
Late blight,caused by Phytophthora infestans(Mont.)de Bary,is one of the most devastating diseases in potato production at present.Understanding whether or not there is A2 mating type of P.infestans in Heilongjiang is helpful for drafting a strategy for late blight control.Samples of potato late blight were collected from the various areas of Daxinganling,Nenjiang,Nehe,Keshan,Hailun,Suiling,Suihua,Bayan,Hulan,Harbin,Shuangcheng,Linkou,and Wangkui for isolation and purification in this research.Totally,124 P...
