摘　　要：[目的]分析豫南地区夏玉米产量与农艺性状的灰色关联度。[方法]对2016年豫南地区3个地点9个玉米新品种的10个农艺性状与产量的关系进行灰色关联度分析。[结果]豫南地区对夏玉米产量影响较大的农艺性状依次是单穗粒重、百粒重、穗行数、出籽率、穗长、穗位高,而株高、秃尖长、倒伏率3个性状对产量的影响则因地区或品种的不同而有所差异。[结论]该研究为豫南地区新品种评价与筛选提供理论依据。[Objective ] To analyze the grey correlation degree of yield and agronomic traits of summer maize in southern Henan Province. [ Meth- od] The relationship between yield and 10 agronomic traits of 9 new maize varieties in 3 localities of southern Henan Province in 2016 was studied by grcy relation analysis. [ Result] Contribution rates of agrenomic characters to maize yield from maximum to minimum were in the order of grain weight per spike, 100-kernel weight, ear row number, seed producing rate, ear length, ear height; while the impacts of plant height, bare top length and lodging rate on grain yield varied clue to difficient alias or varieties. [ Conelusion] This researeah provided theoretieal basis for the evalu- ation and screening of new varieties in southern Henan Province.
