棉花品种主要数量性状与皮棉产量的灰色关联分析

Grey Correlation Analysis of Main Quantitative Traits and lint Yield of Cotton Variety

通过运用灰色关联分析方法对国家棉花品种区域试验中的参试品种(系)邯郸点试验数据进行了主要数量性状与皮棉产量分析。结果表明:对棉花品种皮棉产量影响较大的因素是单株结铃数和衣分,各个因素对皮棉产量的影响程度依次为:单株结铃数>衣分>霜前花率>始果枝节位>单铃重>果枝数>株高>籽指。

Main quantitative traits and lint yield were analyzed by grey correlation analysis in new cotton variety. The re- suits showed that ： the numbers of bolls per plant and ginning outtum were the bigger influence factors to lint yield. The influ- ence degree to lint yields of every factor was as follows： the number of bolls pet plant 〉 ginning outtum 〉 pre - frost yield 〉 the first node of fruit branch 〉 single boll weight 〉 fruit branch number 〉 stem height 〉 seed index.
