摘要
应用灰色关联度分析方法,对云南省多花菜豆品种主要性状对其产量的影响进行分析,结果表明:产量与主要性状的关联度大小依次为生育期>单荚粒数>单株产量>单株荚数>单株粒数>百粒重。与产量形成关系密切的主要性状是生育期、单荚粒数、单株产量,并明确了各性状之间的相互关系,为云南省多花菜豆育种和栽培提供理论依据。
The paper analyzes the correlation degree between the yield of 6 scarlet runner bean (Phaseolus coccineus L.) varieties in Yunnan province and their yielding characters by the method of grey correlation degree analysis. The results show the order of them: growing period > number of grains per pod > yield per plant > number of pods per plant > number of grains per plant > 100-seed weight. Hence, yielding character like growing period, number of grains per pod, yield per plant, keep close relation with yield, which provide a theoretic base for scarlet runner bean production and breeding.
