小麦新品种的灰色关联度分析

The Grey Correlative Degree Analysis of New Varieties of Wheat

本文应用灰色关联度分析法 ,对参加 1 997～ 1 998年度国家黄淮南片小麦品种区域试验春水组 1 0个品种 (系 )的 1 2个主要性状进行了综合描述和量化评估 ,较为全面、客观地评价了参试品种 (系 )的优劣 .笔者认为 ,与等权关联度排序相比 ,加权关联度排序的评估结果更能反映品种产量等多个性状的实际表现 ;

In this article,through grey correlative degree analysis,twelve importment properties of ten varieties (strains),which were chosen from the 1997～1998's spring corn group of wheat variety area test of Southen Huanghuai were generally described and quantatively evaluared.Then the qualities of varieties were objectively graded.Comparing with the epuweighted incidence sequence method,the evaluation of weighted incidence sequence could more accurately reflect many properties such as yield.The selection of control varieties and relative properties is the heart of grey correlative degree analysis.
