摘　　要：为筛选出综合性状好的优良红小豆品种(系),对22个红小豆品种(系)的生育期、株高、底荚高度、主茎节数、主茎分枝数、单株荚数、荚长、单荚粒数、百粒重、产量这10个性状进行变异分析、因子分析和聚类分析。结果表明:结合变异系数和因子载荷可以看出,株高、主茎分枝数、单株荚数、百粒重可以作为红小豆形态要求的选择标准。通过建立综合评价模型,综合评价居前3位的品种(系)是渝红豆4号、保红201219-1、THM2011-28,可作为优异资源加以利用。通过聚类分析,将22个红小豆品种(系)划分为4个大类群,大部分品种(系)聚集在第Ⅰ类群和第Ⅲ类群,以后应加强资源的多样性开发利用。In order to screen out adzuki bean varieties(lines)with good comprehensive characters,variation analysis,factor analysis and cluster analysis were carried out on 10 characters(growth period,plant height,bottom pod height,node number and branching of main stem,pod number per plant,pod length,seed number per pod,100-seed weight and yield)of 22 adzuki bean varieties(lines).The results showed that,based on the coefficient of variation and factor loading,plant height,main stem branching,pod number per plant and 100-seed weight could be used as selection criteria of adzuki bean.Through the establishment of a comprehensive evaluation model,the top three varieties(lines)in comprehensive evaluation were Yuhongdou 4,Baohong 201219-1,THM2011-28,which could be used as excellent resources.Through cluster analysis,22 adzuki bean varieties(lines)were divided into 4 groups,most of them clustered in the group I and the group III.In the future,the diversfied development and utilization of resources should be strengthened.
