【摘要】 经试验比较采自我国海南、吉林、辽宁、山西、贵州等地玉米锈病的症状和病原菌夏孢子形态特征，进一步明确我国目前仍发生有普通型和南方型两种玉米锈病。接种试验表明，目前我国生产和育种上常用的一些杂交种和自交系大多感染普通型玉米锈病，其中“烟单１４号”、“农大６０号”、“黄早四”、“５００３”感病较重。更多还原

【Abstract】 On comparing the symptoms and morphology of summer spores of the corn rust from Hainan,Jilin,Liaoning,Shanxi and Guizhou Provinces,the authors found that the common rust and Southern rust are still frequenting in China. Inoculation tests showed that some hybrids and inbred lines commonly used far growing and corn breeding are susceptible to the common rust;“Yandan 14”,“Nongda 60”,“Huangzao 4”and“5003”are more susceptible ones.更多还原
