应用灰色系统理论综合评估玉米新品种

A Preliminary study on synthelic appraisal of new Corn Varieties applying of the Grey system Theory

本文应用灰色系统理论中的关联度分析方法，对我所1996年玉米新品种比较试验的考查结果进行综合评估，结果与品种实际表现基本一致。证明由于各性状时品种的重要性不同，在给出不同的权重系数时，运用灰色关联分析对玉米新品种进行多性状综合评估比单纯依靠产量结果对参试组合进行评估更具科学性。此法可作为玉米品比或区试中对参试品种进行综合评估的一种有效方法。

Mathematical method of the relational grade analysis of the grey system theory and its application in assessing new corn Varieties was deseribed with a set of data from a comparative test of corn. The results indicate that this new method is simpler and more convenient than any other ones and is also effective
