摘　　要：采用MINQUE[1]统计方法,利用AD模型对8个陆地棉品种及其16个F1组合产量性状的资料进行了相关分析和目标产量性状的决策分析。结果表明,不同性状间遗传组分相关系数的大小顺序并不能代替其他性状对皮棉总产决策系数的大小顺序。从而确定了提高陆地棉中熟与早熟品种间杂种后代皮棉总产的主要决策性状和限制性状。The genetic correlations and decision coefficients on aim yield traits of 8 parents and their 16 F1 crosses of between middle and early Varieties in upland Cotton （G. hirsutum L. ） were analyzed for their additive and dominance effects by MINQUE （ 1 ） approaches. The results indicated that the orders of correlation coefficients on genetic components between different traits could not replace those of the decision coefficients for other traits to total lint yield. The principal decisive and restricted traits were proposed for improving total lint yield of hybrid progeny between middle and early Varieties in upland cotton.
