| 摘 要： | 以43份杂交棉F1代为研究对象,时各杂交组合主要性状竞争优势、相关系教及通径系数进行分析.结果表明:杂交棉F1代中皮棉产量、单株铃数和表分都有较强的竞争优势;时皮棉产量直接作用较大的性状为单株铃数、衣分和单铃重,对F1代的筛选应注重对这几个性状选择,以获得强优势的杂交组合.

| Abstract: | The competitive advantage,the correlation coefficient and path coefficient of the major agronomic traits were analysed,using 43 cotton hybrid F1 as materials.The results showed that cotton lint yield,boll number per plant and lint percentage of cotton hybrid F1 generation had strong competitive advantages.In order to get a strong advantage hybrid combinations,pay attention to these traits which had more direct effect on cotton lint yield,such as boll number per plant,lint percentage,single boll weight. |
