| 摘 要： | 对2005～2007年河北省审定的抗虫棉主要农艺性状进行了灰色关联度分析.结果表明:各农艺性状与霜前皮棉产量的关联度顺序为单株结铃数＞铃重＞霜前花率＞株高＞子指＞单株果枝数＞衣分＞第一果枝节位＞生育期.单株铃数和铃重是影响河北省春播棉区抗虫棉皮棉产量的主要因素.

| Abstract: | Main factors affecting yield of transgenic cotton in Hebei Province were analyzed with the way of Gray Relational Grade.The results showed that the Gray Relational Grade among yield of transgenic cotton and agronomic characteristics in se-quence from the biggest to the smallest is bolls,boll weight,pre frost lint percentage,plant height,seed index,number of fruit branches,lint percentage,the first fruit site and grow stage. |
