| 摘 要： | 利用11个分别含有单抗性基因R1~R11及1个不含抗性基因的1套鉴别寄主,对2003~2005年采自云南省10个县市26个采集点的117个马铃薯晚疫病菌的菌株进行生理小种鉴定。结果表明:共鉴定出26个菌株的生理小种,其中优势小种为3.4.6.8.10.11,占所测菌株的28.69%,主要分布在寻甸、丽江、昆明;其次是3.4.10,发生频率为13.11%,主要分布在镇雄;然后是3.10,发生频率为10.66%,主要分布在宣威。

| Abstract: | 117 isolates came from potato plant of 26 collection areas in 10 counties and cities in Yunnan Province were tested with 11 mono-gene R1~R11 potato clones of potato late blight differential host.The results showed that there are 26 race in Yunnan Province and the dominant race were 3.4.6.8.10.11 with frequency of 28.69%.They were distributed in Xundian,Lijiang,and Kunming;3.4.10 with frequency of 13.11% was distributed in Zhenxiong;3.10 with frequency of 10.66% was distributed Xuanwei. |
