| 摘 要： | 应用典型相关分析方法，对１２０个陆地棉品系产量构成的三个因素进行分段研究表明，（１）构成皮棉产量的三因素间存在动态平衡，不同组合模式，其产量表现不同。（２）单株铃数、衣分、铃重都存在最佳选择范围，在此范围内容易形成高产皮棉的优化组合。（３）三因素中某一因素的过高选择，会降低另外两个因素的选择动态，不易形成最佳产量组合。

| Abstract: | The correlation among the yield traits in upland cotton was conducted by selection model. The results showed that there was a dynamic equilibrium in three yield traits. Different composes of yield trait create different lint yield levels. There was an optimum selection range for three yield traits, and within these range, It likes easily form higher lint yield model. There will reduce the other two yield traits selection levels for one of the three yield traits selected too high, and not lead to the optimun yield combination. |
