| 摘 要： | 通过对45个新疆早熟棉品系的7个农艺性状的相关性和通径分析。结果表明:衣分是决定霜前花皮棉产量最主要的因素,它与霜前花皮棉产量的相关系数和通径系数分别为0.5074和0.6453。籽指与霜前花皮棉产量的相关系数和通径系数分别为-0.2618和-0.1559,仅随其后。在选育新疆早熟棉花品种中,根据各农艺性状对霜前花皮棉产量影响大小并参考各农艺性状之间相互作用,可选育出霜前花皮棉产量高的早熟棉花新品种。

| Abstract: | The main purpose of the study was to carry out genetic correlation and path analysis of seven agronomic traits from 45 Xinjiang Early-maturing Cotton lines.The results indicated that the pre-frost cotton yield was mostly determined by the lint.The correlation coefficient and path coefficent of its pre-frost cotton yield were 0.507 4 and 0.645 3 respectively.The correlation coefficient and path coefficient of seed index and pre-frost cotton yield were-0.261 8 and-0.155 9 respectively.Finally,the early-maturing cotton seeds were selected based on the effect of agronomic traits on pre-frost lint yield and the interactions between different agronomic traits. |
