| 摘 要： | 采用Eberhart和RusseⅡ(1966)的分析模式评价了12个夏芝麻品种(系)产量等10个性状的稳定性,并按Spearman等级相关的方法研究了产量稳定性与其他性状稳定性间的相关关系.结果表明,大多数品种(系)产量等10个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.因此,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.

| Abstract: | Analysis pattern of Eberhart and Russell(1966)was used to evaluate the stability of 10 traits of 12 summer sesame cultivars(lines).and the correlation of yield stability and other traits stability was studied base on methods related to Spearman degree.The results showed that:there was significant or very significant linear relationship between the average performance of 10 traits of most cultivars(Lines) and environmental index,and there was a significant or significant positive correlation between production stability and the number of capsule per plant and between grain weight per plant and height stability.Therefore,the stability of number of capsule per plant,grain weight per plant and height can be the indirect diagnostic information for the stability breeding of summer sesame. |
