摘要： 为探讨大豆主要农艺性状对大豆产量影响的主次关系，运用灰色关联度分析法，对黄淮海地区16 个品种12 点试验进行产量与农艺性状的分析，从而为黄淮海地区大豆育种提供理论依据。结果表明：产量与主要农艺性状的关联度大小依次是单株粒重＞分枝数＞株高＞生育日数＞单株荚数＞单株粒数＞主茎节数＞底荚高度＞百粒重。可见，对大豆新品种选育时，应优先考虑单株粒重，分枝数，株高和生育日数。

Abstract: To explore the effects of major agronomic traits on the yield of soybean, grey correlation degree analysis method was adopted to analyze the yield and agronomic traits of 16 soybean arieties and 12 points test in Huanghuai River Region, which provided a theoretic base for soybean breeding in Huanghuai River Region. The results showed that the order of the correlation degree of yield and agronomic traits was: the weight of seeds per plant ＞ branches per plant ＞ the plant height ＞ growing period ＞pods per plant ＞ the number seeds per plant ＞ main stem node number＞ height of lowest pod ＞ 100 seed weight. When we bred new soybean varieties, the weight of seeds per plant and branches per plant, the plant height and growing period were the prior factors for the yield.
