[ Objective ] The aim was to study yield performance and agronomic characters of maize hybrids. [ Method ] Using randomized block arrangement, twenty-two kinds of maize hybrids were compared. [Result] Six kinds of high yield combination which suit the ecological environment in Peixian were screened. That the main direction of maize hybrid' s cultivation was to increase grain number and grain weight were cleared. The analysis showed that the change in the agronomic characters and the components of yield were consistent with yield performance. [Conclusion] The study provides a theoretical basis for maize high yield cultivation.%[目的]研究玉米(Zea maysL.)杂交新组合的产量表现和农艺性状.[方法]采用随机区组排列的方法,对引进的22个杂交玉米新组合进行了品种比较试验.[结果]筛选出了适合沛县生态环境条件的高产组合6个,明确了高产玉米组合栽培的主攻方向是增加穗粒数和粒重,分析出玉米杂交组合农艺性状、产量构成因素增减变化与产量高低表现均一致.[结论]该研究可为玉米高产栽培提供理论依据.
