| 摘 要： | 试验对陆地棉F1代株内的变异与构成皮棉产量的4个性状进行了研究,并重点对铃重、衣分的横向变异量和纵向变异量与直接构成皮棉产量的4个性状进行了典型相关分析。通过典型变量的筛选,第一对典型变量达到极显著标准,其中铃重的横向变异与单株皮棉产量均具有较大的信息载荷量,但二者方向相反,说明铃重横向变异量大的类型不利于产量的提高。V值应尽可能为小值。

| Abstract: | The variation inside F1 generation plant of upland cotton and the four lint yield related traits were analyzed,in which the relationship between horizontal and vertical variables for boll weight and lint percentage and four lint yield related traits was analyzed by canonical correlation analysis method.By screening the canonical variables,the first pair of the canonical variables reached extremely significant,in which the horizontal variables of boll weight and lint yield per plant had relatively larger volume of information,but there was an opposite direction between them.Therefore,the results indicated that the plant with larger horizontal variables of boll weight can not increase lint yield,and V value should be as small as possible. |
