| 摘 要： | 运用灰色系统理论的关联度分析法,对苦荞区试品种的产量相关性状进行关联度分析。结果表明,苦荞品种与产量相关各性状的灰色关联度大小依次为:株高>株粒重>主茎分枝>主茎节数>千粒重,这为进一步选育高产苦荞提供了一定的理论依据。

| Abstract: | In this article,the author adopted correlation analysis method of grey system theory, and carried out the grey related degree analysis between the buckwheat yield and five other main characters. The result showed that the close degree of the grey correlation among different factors between buckwheat and output was as follows :plant heigh＞grain weight of the per plant＞caulis ramification ＞ the number of caulis burl ＞1000 seeds weight. The mentioned result provided theoretical basis for the further seed selection of high output bitter buckwheat. |
