摘要
应用灰色关联度分析方法,对河南省夏大豆品种进行分析,结果表明:产量与主要农艺性状的关联度大小依次为单株粒重>株高>生育期>荚粒数>单株粒数>百粒重>有效分枝>单株荚数,对夏大豆产量影响最大的是单株粒重,影响较大的是株高和生育期,影响中等的是荚粒数、单株粒数和百粒重,影响较小的是有效分枝和单株荚数,为夏大豆育种和栽培提供了理论依据。
In the paper the con＇elation degree among the main agronomic characters of 11 soybean varieties in Henan province and the yield was analyzed with the method of grey correlation degree. The restults showed the order of them： plant yield 〉 plant height 〉 growing period 〉 number of seed per pod 〉 number of seed per plant 〉 100-seed weight 〉 number of branch 〉 number of pod per plant. Hence, the main characters such as plant yield, plant height and growing period had the close relation with yield,which provided a theoretic base for soybean breeding and cultivation in Henan province.
