摘　　要：为筛选适宜定兴县种植的玉米品种,在河北省定兴县特定气候和土壤条件下,对7个玉米品种进行了性状和产量比较分析。结果表明‘:京单28’叶片光合速率最高,综合性状好,单产达10321.5kg/hm2,产量构成因素为:穗数74025株/hm2,穗粒数395粒,千粒重353.0g。参试品种中‘京单28’和‘郑单958’产量水平显著高于其余5个品种。‘京单28’和‘郑单958’适宜定兴县及光热资源相近区域的玉米高产栽培,对提高单产增总产具有重要意义。In order to select maize varieties suitable for the cultivation in Dingxing County, Hebei Province, China, a comparative field trial on the characters and yield of 7 maize varieties was conducted in 2008 under specific climate and soil conditions in Dingxing County. The leaves of ‘Jingdan28＇ had the highest photosynthetic rate and a good comprehensive character performance, with a highest yield of 10321.5 kg/hm^2. Its yield components were 74025 cobs/hm^2, 395 kernels/spike, and 353.0 g per 1000 kernel weight. The ‘Jingdan28＇ and the ‘Zhengdan958＇ had their kernel yields extremely significantly higher than those of other 5 varieties. Therefore, the 2 varieties were suitable for the cultivation in Dingxing County and other areas with similar light and hot resources to Dingxing County.
