应用灰色关联分析法综合评估大豆品种的初步研究

A preliminary study on multi-factorial evaluation of new soybean varieties by the Grey Relational Grade Analysis Method

本文利用大豆区域试验资料探讨了灰色关联分析法在新品种综合评估中的应用.通过分析表明,这种综合评估结果与品种的实际表现较一致.同时认为,在育种上按性状的重要程度赋于不同权重的方法,可提高选择效果.

Mathematical method of the relational grade analysis of the greysystem theory and its application in assessing new soybean varieties was studiedwith a set of data from the regional test of soybean. The analysis results indica-ted that they were similar to actual expression of soybean varieties. Meanwhile,the method by giving different measure on importance of characters in breedingcould increase effects of selection.
