摘　　要：为明确粳糯产量构成因素对产量的影响,采用灰色关联度法对15份粳糯种质的11个产量相关性状进行综合评价。结果显示,产量构成性状与产量的关联度值表现为:有效穗数>结实率>实粒数>总粒数>株高>千粒质量>生育期>剑叶宽>穗长>剑叶长,关联度值分别为0.7856、0.7382、0.7238、0.7105、0.7089、0.6752、0.6737、0.6675、0.6613、0.6555。灰色关联度综合分析结果表明,粳糯稻产量育种应注重有效穗数、结实率、实粒数以及总粒数的选择。In order to ascertain the influence of yield components on glutinous geng rice yield,grey correlation degree analysis was used to comprehensively evaluate the 11 yield-related characters of 15 glutinous rice germplasms.The results showed that grey correlation degree between yield components and yield in descending order were effective panicle>seed setting rate>filled grain number>total grain number>plant height>thousand-grain weight>growth period>flag leaf width>panicle length>flag leaf length,and their correlation degree values were 0.7856,0.7382,0.7238,0.7105,0.7089,0.6752,0.6737,0.6675,0.6613 and 0.6555,respectively.Comprehensive analysis of grey correlation degree indicated that breeding of high-yield glutinous rice should focus on the selection of effective panicle,seed setting rate,filled grain number and total grain number.
