为更好地服务于适宜间作的耐阴性大豆品种的选育，采用灰色关联度分析法，对20个大豆品种的产量及农艺性状进行了分析。结果表明：与大豆产量相关的8个主要农艺性状的关联顺序为株高＞主茎节数＞底荚高度＞有效分枝数＞有效荚数＞百粒重＞单株粒数＞单株粒重。说明，株高、主茎节数是影响产量形成的主要因子，并明确了各性状之间的相互关系，为贵州省耐阴大豆的育种提供了理论依据。

In order to better serve the breeding work with shadow resistance soybean varieties suitable for intercropping,the yield and agronomic characters of 20 soybean varieties were analyzed using the grey relational grade analysis methods.The results showed that eight major agronomic characters related to yield were in following sequence:plant height > nods on main steam > bottom pods height > effective branches> number of effective pods>100-grain weight> grains per plant>weight per plant,indicating that plant height,nods on main steam were the major factors affecting the formation of production,which would provide a theoretical basis for shade-tolerance of soybean breeding in Guizhou.
