摘要
对17个杂交棉品种的产量与产量构成因素性状、生育形态性状、抗病性状及纤维品质性状组间的典型相关分析,明确了各个性状间的相关关系,据此优化了皮棉产量在1500～1725 kg/hm^2的高产优质杂交棉选育模式参数,并对各类性状间的有机联系和协调发展进行了讨论。
Canonical corelation analysis was carried out on the 17 cross - bred cotton varieties＇ yield and yield forming elements, bearing state, antivirus characters and fiber quality characters to nail down the corelations among every character. Accordingly the parameter of lint yield at 1500 - 1725 kg/hm^2 was bettered in patterned selective cultivation of good quality cross - bred cotton. At last a discussion was made on the organic relations and harmonious development among all the characters.
