摘　　要：交配型是马铃薯晚疫病菌重要的群体结构特征之一。中国在内蒙古、云南、河北、四川、重庆、甘肃、黑龙江、福建和宁夏等省份先后发现A2交配型,且在A2交配型出现后几年内发生A2交配型频率急剧下降甚至消失的状况,之后A2交配型的频率则鲜有升高,而自育型与A1A2型菌株则开始出现。最后,对交配型变化的规律与今后的研究方向提出了一些建议,以期为晚疫病菌交配型研究和晚疫病防治提供参考。Mating type is one of the important population structures of Phytophthora infestans.A2 mating type was found in Inner Mongolia,Yunnan,Hebei,Sichuan,Chongqing,Gansu,Heilongjiang,Fujian and Ningxia Provinces(Municipality).And in a few years after A2 mating type was found,the frequency of A2 mating type dropped or even disappeared.Afterward,A2 frequency of mating type rarely increased,but self-fertility and A1 A2 types began to appear.Finally,patterns of changes in mating type and the future research priority were suggested in order to provide reference for the mating type research of Phytophthora infestans and prevention of late blight.
