为了明确早熟大豆品种产量与主要农艺性状间的关联性，利用灰色关联度分析法，对16个早熟大豆品种的产量及农艺性状进行分析。结果表明：与大豆产量相关的6个主要农艺性状的关联度为：单株粒数＞百粒重＞单株荚数＞株高＞节数＞分枝数。说明单株粒数对早熟大豆的产量影响最大，其次是百粒重和单株荚数，而株高、节数、分枝数影响较小。所以在早熟大豆育种时，应该侧重于选择单株粒数多与百粒重大的品种或植株。

In order to define the correlations of early-maturing soybean varieties between yield and main agro-nomic traits ,the yield and agronomic traits of 16 soybean varieties were analyzed by grey relational grade analy-sis methods .The results showed that the correlation of six mayor agronomic traits which related to yield was grain number>100-seed weight>pod number> height> node number> branch number ,it indicated that grain number per plant had the greatest influence on yield of early-maturing soybean ,the height ,node number and branch number had less effect on yield .Therefore grain number per plant and 100-seed weight should be fo-cused on the selection of plant on breeding early-maturing soybean .
