对166个玉米自交系以及抗黄曲霉菌的自交系RA与感黄曲霉菌的自交系M5P杂交获得的79个F2:3家系进行黄曲霉菌抗性鉴定。结果表明:不同自交系接种后的发病级别不同,在166个自交系中发病级别最高的达到10级,而最低的级别为2.4级,绝大部分自交系发病级别较高,基因型不同的材料对黄曲霉菌的抗性差异极显著;在79个F2:3群体中,抗性较强(1～3级)的家系只有2个;有7个家系基本不存在任何抗性(8～10级);51个家系的抗性较弱(5～8级);20个家系的抗性水平中等(3～5级),整个群体抗性水平接近正态分布,这表明通过开展抗性育种工作可提高玉米对黄曲霉菌的抗性。

以6个对黄曲霉菌抗性不同的玉米自交系完全双列杂交所获得的6个世代的种子,用黄曲霉菌接种,调查病级,研究玉米抗黄曲霉菌的基因位点及效应。结果表明:参试的6个亲本自交系之间对黄曲霉菌的抗性有较大差异,不同亲本组配的杂种F1对黄曲霉菌的抗感表现不同。各家系的分离群体中抗感个体的分离,少部分呈有规律的分离比例,而大部分组合的分离群体不呈有规律的分离比例,说明玉米对黄曲霉菌的抗性遗传既有主基因效应,也有多基因效应。多基因遗传体系中,既有基因的加性效应、显性效应,还有上位性效应。6个自交系中,可检测到5个对黄曲霉菌有抗性的基因位点,在自交系RA中携带1个效应较大的抗性基因,而其他几个自交系仅携带1~2个效应较小的抗性基因。自交系RA除可用于抗黄曲霉菌玉米新品种的选育,也可用于发展作图群体对玉米抗黄曲霉菌基因进行定位。
