摘　　要：分析了12个夏芝麻品种(系)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它性状稳定性间的相关关系.分析结果表明,大多数品种(系)数量性状的平均表现与环境指数呈显著或极显著的线性关系.产量的稳定性与单株蒴数、单株粒重及株高的稳定性呈显著或极显著正相关.单株蒴数、单株粒重和株高的稳定性可作为夏芝麻稳产性育种的间接依据.The stability of 10 quantity characters in 12 summer seasame varieties were analyzed by the method of regression coefficient, and the correlated relationship of yield stability and other character stability were demonstrated by correlated analysis, the results showed that the mean performance of quantity characters in most varieties had significant or greatly significant linear relation with environmental index. The yield stability had significantly positive correlation with the number of capsules per plant ,weight of per plant and plant height. The stability of the number of capsules per plant, weight of per plant and plant height may be used as the basis of indirect selection for yield stability breeding of summer seasame.
