就灰关联分析法的基本原理和方法在农作物品种综合评判中的应用问题进行了探讨，提出了使用灰关联分析法进行农作物品种综合评判的具体做法与步骤，并以鲁西北棉区两熟的小麦配套品种（系）为例，进行了具体的评价计算．计算结果全面客观，切合实际，克服了以往评判中只注重某一或某几种性状而忽视其它性状所造成的偏差，表明灰关联分析法是进行农作物品种综合评判的一种便于操作的、科学的、有效的方法 This paper discussed the application of the basic principles and methods of gray relational analysis in the comprehensive evaluation of crop varieties and put forward the specific methods and steps for the comprehensive evaluation of crop varieties using gray relational analysis method. Wheat varieties (lines), for example, conducted a specific evaluation calculation. The calculation results are objective and realistic, and overcome the deviation caused by the neglect of other traits by focusing on one or more traits in the past. It shows that the gray relational analysis is a kind of easy-to-operate scientific evaluation of crop varieties. The effective method
