摘  要:
2012~2013年,采用田间人工接种的方法对新引进的164份国外玉米种质和122份国内常用玉米种质资源进行了玉米弯孢叶斑病的抗性鉴定与评价。鉴定结果表明:玉米种质对弯孢叶斑病的抗性表现存在差异,总体对弯孢叶斑病的抗病能力较低,表现抗病的种质较少,仅有57份,且抗性种质以中等抗病为主,其余229份种质表现感病或高度感病;新引进的国外玉米种质对弯孢叶斑病的抗病能力高于国内常用玉米种质的抗病能力,从新引进的国外玉米种质中筛选出了37份抗性种质,为抗病育种提供了重要基础材料。

摘  要:
During 2012- 2013,a total of 164 maize germplasms introduced abroad and 122 domestic maize germplasms resources had been identified and evaluated for resistance to maize curvularia leaf spot. The results suggested that: the introduced maize germplasms showed significant difference in resistance to maize curvularia leaf spot. However the curvularia leaf spot disease resistant ability was low. The introduced maize germplasms showed only 57 copies,and the resistant germplasms were mostly middle resistant to the diseases,the remaining229 germplasms were susceptible or highly susceptible. The disease resistant ability of foreign maize germplasms of curvularia leaf spot was higher than that of the domestic maize germplasms. The introduction of newly screened 37 resistant germplasms abroad maize germplasms could be utilized for future disease resistant breeding.
