| 摘 要： | 用投影寻踪回归（PPR）分析黄准棉区10个代表性品种的皮棉产量组分性状贡献，结果表明第1贡献因子并非株铃数，而是衣分。同时发现对非正态分布的数据，使用相关分析和通径分析，结果不可靠。

| Abstract: | Projection pursuit regression technology was used to analyze character contribution of yield components of 10 representative varieties. The results show that:(1) the first element is not the quality of boll per plant,but the ginning outturn.(2) error results would be found if the correlation analysis and path analysis were used excessively in views of the abnormal distribution data. |
