试验以河南主推的玉米为材料，分别在豫东、豫中、豫中南、豫南、豫北各生态区选用大田进行试验，研究不同基因型玉米间作对玉米多种抗病性与产量的影响。结果表明，各生态区玉米间作较单作在南方锈病、褐斑病、弯孢叶斑病方面表现出一定的抗病性。豫东：蠡玉16‖浚单22，群体平均抗病率26.02%；豫中南：蠡玉16‖浚单22，群体平均抗病率10.29%；豫中：登海602‖郑单958，群体平均抗病率28.11%；豫北：登海602‖郑单958，群体平均抗病率45.44%；豫南：登海602‖郑单958，群体平均抗病率33.29%。两种基因型玉米间作后增产效果不明显。

Henan main maize was used as the material for test, field experiment was conducted in the eastern, central south, central, southern, and the northern of Henan province respectively, to study the different genotype maize intercropping effects on a variety of disease resistance and yield. The results showed that, each zone on the Southera maize rust, Physoderma brown spot, Southera Curvularia leaf spot after maize interplanting showed some resistance. On the whole, the production increased effect is not particularly obvious after two genotypes intercropping maize. The key is determined by the combination of intercropping maize. Among them, Eastern of Henan:Liyu 16‖Xundan 22, the group of average disease resistance rate was 26.02%; Central South of Henan:Liyu 16‖Xundan 22, the group of average disease resistance rate was 10.29%; Central of Henan:Denhai 602‖Zhengdan 958, the group of average disease resistance rate was 28.11%; Northern of Henan:Den hai 602‖Zhengdan 958, the group of average disease resistance rate was 45.44%; South of Henan:Denhai 602‖Zhengdan 958, the group of average disease resistance rate was 33.29%.
