摘要 [目的]分析江苏地区玉米品种植株性状的相关性，并探讨环境因素对玉米植株性状的影响。[方法]在江苏盐城大丰市开展玉米植株性状相关性试验，采用随机区组试验设计，播种密度6.75万株/hm2;在江苏省宿迁市沭阳县、连云港赣榆县和徐州丰县开展环境因素对玉米植株性状的影响试验，播种密度6.75万株/hm2。[结果]比较不同品种的植株性状，发现不同类型的品种间穗下节间数、穗上节间数、地上总节数、株高、穗位高等植株性状显著不同;品种的生育期与植株的地上总节数和穗下节数呈极显著正相关，株高与植株的总节数呈显著正相关，穗位高与植株的穗下节数呈显著相关。对3个地点的植株性状和环境因素分析后发现，穗上节数受环境影响小，积温与株高、地上总节数呈极显著正相关，积温与穗位高呈显著正相关;降雨量与株高、穗位高、穗上节数、穗下节数、地上总节数呈正相关，其中与株高呈显著正相关。[结论]该研究可为江苏省玉米新品种选育及高产栽培提供参考。

Abstract [Objective] Relevancy of plant traits of different maize varieties in Jiangsu was
analyzed， and impact of environmental factors on plant traits explored. [Method] Relevancy test of maize plant traits was conducted in Dafeng， Yancheng City， Jiangsu Province by adopting randomized block test， and sowing density was 67 500 plants/hm2; impact test of environmental factors on maize plant traits was conducted in Shuyang County （Suqian City）， Ganyu County （Lianyungang City）， Fengxian County （Xuzhou City）， sowing density was 67 500
plants/hm2. [Result] Plant traits of different varieties were compared， below-ear internode number， above-ear internode number， aboveground node number， plant height， ear height of different varieties varied greatly; growth season showed extremely significant positive correlation with aboveground node number and below-ear internode number， plant height showed significant
positive correlation with total node number， ear height showed significant positive correlation with below-ear internode number. By studying plant traits and environmental factors in the 3 locations， it
