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。
Taking the regional trial of wheat in Shandong and Jiangsu Provinces as an example, the issue of how to evaluate the varieties fairly and reasonably in variety validation was discussed. (1) The accuracy of variety test: It is recommended to use CV≤Dn / 2 / tα to estimate. (2) Statistical model of joint analysis of variance Problem: A joint analysis of variance that considers the conversion of years and pilots to environmental factors is a better model. (3) Adaptability and stability analysis: It is proposed that b_i is an adaptive parameter and a_i is a stability parameter. (4) reasonable evaluation of varieties: Recommended parameter group estimation method.
