摘要
运用灰色关联度分析法,对2004-2005年芸豆区域试验（4个组）的参试品种8个数量性状与产量进行分析。结果表明,误差变异系数（CEV）低于12%的平均值为8.9%,小于10%,总体上试验误差控制得较好,数据可信;半蔓生（北方组）、直立（北方组）、直立（西南组）的各性状与产量的关联度大小排序基本一致,前3位都为生育日数、荚长、荚粒数,半蔓生（西南组）前三位为株高、荚长、百粒重,说明环境条件对半蔓生型芸豆的产量与各性状关系有一定影响。
The relationship between kidney bean yield and 8 other traits of tested gnetic types from 2004 and 2005 regional experiments was analysed by means of grey correlative degree.The results showed that the average of the error coefficient of variation（CEV） with lowering 12% of the regional kidney bean trial 4 groups was 8.9%,which generally showed the regional kidney bean trial was controlled preferably and the data of 2004 and 2005 regional experiments was credible,the size orders of grey correlative degrees of yield and yield traits of trailing type（north group）,erection type（north group）,erection type（southwest group） were consistent on the whole and the first three sizes of which generally were growing period,bean length,seed/pod no,the first three sizes of grey correlative degree of yield and yield traits of trailing type（southwest group） generally were plant height,bean length,100-seed weight,which showed the relationship between yield and other traits of trailing type kidney bean was definitely affected by environment.
