摘要
玉米灰斑病是由尾孢菌(Cercospora)侵染引起的一种世界性病害。本研究采用尾孢菌特异引物对采自西南地区经过单孢纯化的17个玉米灰斑病菌菌株进行了分子鉴定,结果表明:采集自西南地区的玉米灰斑病样本分离得到的菌株都为Cercospora zeina;未检测到玉蜀黍尾孢菌Cercospora zeae-maydis。这就说明,引起西南地区的玉米灰斑病主要致病种为Cercospora zeina。
Gray leaf spot (GLS), caused by the causal fungal pathogen Cercospora, is one of the most serious foliar diseases of maize world- wide. Molecular identification of 17 isolates of Cercospora, collected from the corn planting regions of Southwest China of Cercospora species was conducted using the species-specific primer. The results showed that 17 kinds tithe gray leaf spot pathogens collected belonged to Cerco- spora zeina. There's no Cercospora zeae-maydis. Gray leaf spot (GLS) was mainly caused by Cewaspora zeina in Southwest China.
