摘要: 串珠镰刀菌(Fusarium monilifome Sheldon)引起的玉米穗粒腐病近年来已成为我国玉米上的主要病害之一。试验结果证明,自交系的抗病性有很大差别,可由高抗到高感,二南24和330是高抗的,Mo20和Mo17是感病的。五对具有正常的和奥帕克-2(简称O2)基因的玉米自交系用串珠镰刀苗接种证明,除高抗系外,O2系明显比正常的感病。F1的抗病性是超亲的或倾向抗病亲本的。抗×抗和抗×感的F1都是抗病的,感×感的表现不十分感病。

关键词: 玉米, 奥帕克-2, 串珠镰刀菌

Abstract: The kernel rot caused by F.monili fame is one of the most serious diseases of corn in recent years in Chine.The experimental results showed that the inbred lines differ widely in their resis-tance.The lines Ernan-24 and 330 were very resistant;Mol7 and Mo20 were suscepti-tible.5 inbred lines of normal and Opaque-2 genotypes were inoculated with isolates of F.monilifome.Opaque-2 were less resistant than the normal types.The R×R(resistant)and R×S(susceptible)cross were resistant,S×Scross were not very susceptible.

Key words: Corn, Opaque-2, Fusanum monilifome
