摘要
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。
This paper deals with the application of grey relativity analysis method to comprehensive evaluation of crop varieties, and introduce application of this method. With a calculation example, the wheat varieties of double crop wheat and cotton in the Nouthwest of Shangdong Province is comprehensively evaluated by use of this medthod, and the results are in good agreemeet with reality. This method also avoids experimental deviation induced by placing extreme stress on partial crop traits while neglecting other characters. It is indicated that grey relativity analysis is one of the easy, rational and effective methods in comprehensive evaluation of crop varieties.
