| 摘 要： | 按Eberhart和Russell(1966)的分析模式评价了八个陆地棉品种(系)皮棉产量等十个性状的稳定性。同时,采用Spearman等级相关的方法研究了皮棉产量稳定性与其他性状稳定性的相关关系。结果表明,分析的大多数品种(系)皮棉产量等十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,皮棉产量的稳定性(平均产量对环境指数的回归系数)与单株成铃数和衣分的稳定性呈密切的正相关关系,与株高和果枝始节的稳定性亦呈显著的正相关。因此,进行稳产性育种可根据铃数、衣分、株高和果枝始节的稳定性进行间接选择。

| Abstract: | The stability of Upland cotton (Gossypium hirsutum L.) was studied forlint yield,boll number/plant,boll weight,lint percentage,seed index,lint index,plantheight,sympodial branches/plant,node of the first sympodial branch and maturing period,following the regression approach of Eberhart and Russell (1966) . Most of the variationswith the changes in environment could be accounted for by the linear regression on theseenvironmental indices. Based On the above, it was proposed that spearmans rankcorrelation may be used to study the association of stability parameters among characters.The results showed that stability of lint yield was positivety correlated with stabilityof boil number/plant, lint percentage,plant height and node of the first sympodialbranch. |
