摘要
应用灰色关联度分析法,对邯郸市农业科学院培育的30个杂交棉新品种的产量及其相关因素进行了分析。结果表明:衣分、霜前花率和株高与产量的关联度居前3位,节位、单株果枝数、单铃重和单株成铃数与产量的关联度较高,病株率和病情指数与产量的关联度较低。该研究可为棉花杂种优势利用研究提供理论依据。
The yield and main agronomic characteristics of thirty hybrid cotton varieties which were bred by Handan Academy of Agricultural Sciences were studied using the grey relational grade analysis. The results showed that the relational grades between the lint percentage, pre-frost yield percentage, the individual plant height and yield were arranged in the top three, between boll number per plant, node, single boll weight, branch number per plant and yield were higher, while the relational grades between disease index, disease plant of percentage and yield were lower. The study could provide theoretical basis for utilization of cotton heterosis.
