采用相关分析和通径分析，对四川10年来育成品种（组合）的单株铃数、单铃重、衣分与皮棉产量的关系进行了分析。其中常规棉各结构因素与皮棉产量均为极显著正相关，而杂交棉仅衣分达极显著正相关，表明杂交棉的产量潜力比常规棉大。在对皮棉产量比CK增产5％以上的常规棉和增产10％以上的杂交棉的分析中，铃重与皮棉产量均为负相关。表明常规棉和杂交棉高产潜力的进一步改良，重点应提高结铃数和衣分。
Correlation analysis and path analysis were used to analyze the relationship between boll number, boll weight, lint yield and lint yield of bred varieties (combinations) in Sichuan in the past 10 years. Among them, the structural factors of conventional cotton were significantly and positively correlated with the lint yield, while the hybrid cotton only had a very significant and positive correlation, indicating that the yield potential of hybrid cotton was larger than that of conventional cotton. In the analysis of conventional cotton yield more than 5% of lint yield and CK more than 10% yield, boll weight was negatively correlated with lint yield. Indicating further improvement of the high yield potential of conventional and hybrid cotton, with the focus on increasing number of bolls and lint.
