灰色关联分析方法的基本思想是根据所研究因子间在动态变化中其变化的相似程度来判断因子间的密切程度,关联度是反映这种密切程度大小的度量,关联度越大说明因子间变化的势态越接近,其相互关系越密切。高产育种是大豆主要育种目标之一,然而,数量性状是决定产量的主导因素,因此,必须研究限制产量因子间的关系,以使能合理准确的选择。本文探讨灰色关联分析方法
The basic idea of gray relational analysis is to determine the closeness of the factors according to the similarities of the changes of the studied factors in the dynamic changes. Relevance is a measure reflecting the closeness of the factors. The bigger the correlation is, The closer the trend is, the closer it is to each other. High-yielding breeding is one of the major breeding objectives of soybean. However, quantitative traits are the dominant factors in determining yield. Therefore, it is necessary to study the relationship between yield factors to limit the reasonably accurate selection. This article explores the gray correlation analysis method
