摘要
对黄淮地区３６个夏大豆品种及品系的产量构成因素、生育特性、开花结荚动态及产量的空间分布进行了研究．单株产量与粒数、荚数、株高、主茎节数呈显著或极显著正相关，与结荚高度呈极显著负相关．株高、主茎节数、荚数、粒数对产量有较大的正向直接作用．结荚高度对产量有较大的负向直接作用．早花型品种产量水平较高，高产品种均为亚有限结荚习性，其产量空间分布为垂直分布均匀型和水平分布主茎型．
Abstract varieties summer planted soybean were used to analyze their yield components, growth and develpoment characteristics, flowering and poddiug habits, and yield d istribution. As the results,the single plant yield positively correlated with number of seeds,number of pods,plant height and node number of main stem at 5% or 1 % level,but it negatively correlated with height of the first pod at 1 % level. Path analysis showed that plant height,node number of main stem,number of pods and seeds had positive and direct effects on yield,while the pod height had negative and direct effect on it. High yielding varieties mostly had sub limit podding habits, their yield distribution belonged to uniform distribution type in vertical direction and main stem type in horizontal direction.
