摘　　要：以山东和江苏的小麦区试为例，探讨了品种审定中如何公正合理评价品种的问题。（１）品种区试的精确度标准：建议采用ＣＶ≤Ｄｎ／２／ｔα来　估计。（２）联合方差分析的统计模型问题：认为年份和试点转换为环境因素的联合方差分析是较好的模型。（３）适应性和稳定性分析：提出ｂ＿ｉ为适应性参数，ａ＿ｉ为稳定性参数。（４）合理评价品种：推荐采用参数分组估计法。A set of wheat cultivar regional test data in Jiangsu and Shandong Provinces were used as examples to demonstrate the analysis methods.The following problems with rational evaluation of cultivars in registration are discussed.(1) The precision of cultivar regional tests:We proposed that the scale might be measured by (2) The statistical model in complex analysis of variance:The complex variance analysis for environments and cultivars in regional tests might be a better model.(3)Stability and adaptability parameter: The b_i may be expressed adaptability parameter,and a_i is a stability parameter.4. Rational evaluation of cultivars: It is suggested that the grouping estimation of parameter analysis might be adopted.
