Abstract: In order to optimize the wheat-maize double cropping system from the perspective of maize (Zea mays L.) varieties, maize varieties Jinhai No.5, Zhengdan 958 and Xianyu 335 were selected as experimental materials and planted in early summer in Jiaodong region, and their basic traits were compared and studied. The results showed that the number of leaves of Jinhai No.5 was significantly lower than that of Zhengdan 958 and Xianyu 335; In plant height, XY335 was significantly higher than that of Zhengdan 958 and Jinhai No.5; In lodging resistance, Jinhai No.5 and Xianyu 335 were better than Zhengdan 958; In growth traits of maize ears, Zhengdan 958 was better than Xianyu 335, while Jinhai No.5 was the worst; In resistance to corn borer, the order from strong to weak was Zhengdan 958, Jinhai No.5 and Xianyu 335; In theoretical yield, there was no considerably difference among three varieties; In disease resistance, Zhengdan 958 was less resistant to maize head smut. In conclusion, Xianyu 335 is an ideal maize variety for early summer planting in Jiaodong region, China.
