摘要:

利用美国A632,B37,B73,B68,C103,Va26等30个Ht单基因鉴别寄主, 按美国伊利诺伊大学的大田接种方案与鉴定方法, 建立了适合中国的监测玉米
大斑病菌生理小种鉴定的21个Ht单基因系. 从吉林省15个地区的不同玉米品种中采集玉米大斑病样本, 采用单孢分离获得了32个玉米大斑病菌菌株, 利用已建立的上述21个Ht单基因鉴别寄主, 通过美国的大田鉴定方案进行生理小种鉴定. 结果表明, 这32个菌株均为0号小种, 并未出现生理小种分化现象.

关键词: 单基因系; 玉米大斑病菌; 生理小种; 鉴定

Abstract:

Thirty inbred lines such as A632, B37, B73, B68, C103 and Va26 from the inbred collection at the University of Illinois  were used to determine physiological races of Exserohilum turcicum in the field. Twenty\|one inbred lines from the inbred collection were selected to dete
rmine physiological differentiation of E.turcicum effectively in China.  Thirty\|two single conidial isolates of E.turcicum were collected th
roughout 15 farming areas of Jilin Province. All the 32 isolates were race zero. There was no physiological differentiation of the pathogen.

Key words: inbred lines, Exserohilum turcicum, physiological races, identification
