摘　　要：以黄淮海夏播玉米区2002～2009年区试数据为依据,分析实体对照的局限性,将参试品种平均值作为对照与实体对照进行比较。结果表明,玉米品种区试中采用参试品种平均值作为对照是可行的。采用平均值作对照的同时可在区域试验中加入本区或当地大田表现较好的品种作为参照,有利于考察参试品种对环境的实际适应能力。在区域试验中可采用平均值作对照,但生产试验和预备试验中一般不宜采取平均值作对照,应用实体对照。选拔标准一般可参照现行的审定标准,但不同生态区域和组别有所不同,需要综合考虑各区情况。Based on data of summer maize areas of Huang-huai-hai from 2002 to 2009, this paper analyzed the limitations of physical control, and used the average of the testing varieties as the control variety. The results showed that the average of the testing varieties as the control may be suitable for Plot trial, not for field test or primary test. Used the average as control in the regional test field added to the district or local varieties performed better as a refer- ence, is conducive to study varieties tested the actual ability to adapt to the environment. That can be used in the aver- age regional test for the control, but the production testing and preliminary trials in general should not take the average as the control, should be used entity to control. Selection criteria generally refer to the current certification standards, but groups of different ecological regions and different needs to consider various circumstances.
