摘要
通过对黑龙江省5个地区12个县市的马铃薯晚疫病菌生理小种的鉴定,鉴定出黑龙江省马铃薯晚疫病菌生理小种有14种类型,分别为0号、1号、2号、3号、4号、5号、7号、9号、11号、1 2号、2 3号、2 4号、3 4号、1 2 3 4号,其中分布最为普遍是0号、4号和11号生理小种。与60年代相比,新出现的有10个小种:3号、5号、7号、9号、11号、1 2号 2 3号、2 4号、3 4号和1 2 3 4号。
The leaf samples with typical late blight(Phytophthora infestans)symptoms were collected in 12 counties of 5 prefectures of Heilongjiang province,and the physiological races were identified by using host plants,which were provided by CIP.Fourteen physiological races were found,that is 0,1,2,3,4,5,7,9,11,12,23,24,34,and 1234,of which the physiological races,0,4,and 11,were widely distributed.Compared with 1960's,ten new physiological races,3,5,7,9,11,12,23,24,34,and 1234,occurred.
