采用相关分析和通径分析,研究了陆地棉主要性状间的相关关系及各性状对选择皮棉产量的效果。相关分析结果表明,果始高与果枝数呈显著相关,果始节与果始高之间呈极显著正相关,单铃重与籽指、单铃重和衣分之间呈极显著负相关;衣分与皮棉产量呈显著正相关,籽指与皮棉产量的负相关达极显著水平。通径分析结果表明,衣分可直接用于皮棉产量的选择,其他性状不能直接用于皮棉产量的选择。9个植株性状对皮棉产量的选择效果为衣分〉生育期〉果枝数〉果始节〉单株铃数〉果始高〉籽指〉单铃重〉株高。

By using correlation analysis and path analysis,the author analyzed the main characters correlation of upland cotton and the selection effect of yield.The results showed that,fruit beginning height has significant correlation with fruit branch numbers.Fruit section beginning has a very significant positive correlation with fruit beginning high,single boll weight and 100 seeds weight,single boll weight and fiber yield have very significant negative correlation;fiber yield and lint yield have a significant positive correlation,100 seeds weight refers to the negative correlation with lint yield at the significant level.Path analysis showed that,fiber yield can be applied directly to the choice of lint yield,other properties cannot be directly used for the choice of lint yield.9 planting plant traits on the choice effect of lint yield ： fiber yieldgrowth periodfruit branch numbersfruit section beginningthe boll numberfruit beginning height100 seeds weightsingle boll weight plant height.
