摘 要 ：1997～1998年选取山西省当前推广和拟推广玉米杂交种及亲本自交系,采用自然感染与人工接种相结合方法,对MDMV抗性和F1抗性遗传进行了研究,旨为选育推广抗病品种提供依据.试验结果表明,双亲抗×抗、感×抗,其杂种F1抗性表现显性效应,F1病情指数0～8.2,均可达到抗病保产的目的,但感×抗必须在无病区制种才能获得成功.试验认为抗×抗是选育抗MDMV杂交种最佳组配方式,感×抗应视为过渡组配方式加以利用,而感×感,F1病情指数31.9～37.5,产量损失严重,应禁止在病区制种与推广.

Abstract:In order to provide basis for extending maize disease resistant varieties, the experiments of the resistance of the hybrids and inbred lines and their resistant inheritance of F1 were conducted during 1997 - 1998. These hybrids and inbred lines were relea
