摘要： 分析了13个夏大豆品种的10个数量性状的稳定性，同时采用相关分析法论证了产量稳定性与其他稳定性间的相关关系。分析结果表明，大多数品种数量性状的平均表现与环境指数呈显著的线性关系或极显著的线性关系；产量的稳定性与单株粒数、单株粒重及株高的稳定性呈显著正相关。单株粒数、单株粒重和株高的稳定性呈显著正相关。单株粒数、单株粒重和株高的稳定性，可作为夏大豆稳产性育种的间接选择依据。

Abstract: The stability of 10 quantity characters in 13 summer soybean varieties were analyzed by method of regression coefficient and the correlated relationship of yield stability and other character stability was demonstrated by correlated analysis.Results showed that the mean performance of quantity characters in most varieties had significant or greatly significant linear relation with environment index.The yield stability had significantly positive correlation with that of grains of plant,weight of plant and plant height.The stability of grains of plant,weight of plant and plant height may be used as the basis of indirect selection for yield stability breeding of summer soybean.
