摘　　要：利用方差分析法和灰色关联度法对2002年国家区域试验的玉米杂交种在长春地区的表现进行了分析和评价。结果表明:DH3660、强盛1号、三北6号、CAu918、M131和永31433在产量和其他农艺性状上表现较好。这些品种在本地区均有一定的增产潜力。将2种分析方法结合起来对品种加以考察效果更好。By mathematical methods of variation analysis and grey correlative analysis, some new corn hybrids for national regional experiment were evaluated. The experiment was conducted in Changchun in 2002 to study the performance of their yield and other characters in this area. The results indicated that yield and other agronomic characters were ideal in DH3660, Qiangsiheng 1, Sanbei 6,CAu918, M131 and Yong31433. These hybrids were of high yield. In addition, the evaluating effectiveness could be better using the two methods.
