摘　　要：采用相关分析和灰色关联度分析相结合的方法,对28个绿豆品种(系)农艺性状与产量的关系进行综合评价,研究绿豆品种农艺性状与产量的关系。结果表明,生育期、株高、主茎节数、单株荚数与产量呈显著正相关;不同农艺性状与产量的关联度依次为单株荚数>荚粒数>百粒重>主茎节数>主茎分枝>荚长>生育期>株高。2种分析方法均表明,单株荚数对产量的影响最大,因此在育种实践中应优先考虑单株荚数这一因素,同时将两种方法相结合,对品种进行综合客观评价。The relationship between the agronomic traits and yield of 28 mung bean varieties(lines)was comprehensively evaluated by correlation analysis and grey correlation analysis.The results showed that the growth period,plant height,node number of main stem and pod number per plant had significant positive correlation with yield.The correlation degree between different agronomic traits and yield were pod number per plant>pod number>100-seed weight>node number of main stem>branch of main stem>pod length>growth period>plant height.Both of the two methods showed that pod number per plant had the greatest influence on yield.Therefore,pod number per plant should be given priority in breeding practice.At the same time,the two methods should be combined for comprehensive and objective evaluation of varieties.
