摘　　要：根据1996～2003年河北省春播玉米区域试验资料,对先后承担区域试验的15个试验点判别品种的能力和产量结果的代表性进行了分析。结果表明,有5个试点是理想的试点,4个是较理想的试点;试点产量水平的高低不影响其判别能力和代表性;理想试点组合的判别能力和代表性都高于单个试点。Based on the data of regional test of spring maize varieties in Hebei province during 1996-2003, this article analyzed the ability to distinguish various varieties and representation of 15 test sites. The results showed that five sites are the best ones and four sites are the better ones. The site＇s yield level doesn＇t have effect on its distinguishing ability and representation. Combination of suitable sites has higher distinguishing ability and representation than that of single site.
