摘 要 ：对30个小豆品种的11个形态性状进行了因子分析及聚类分析。结果表明，11个形态性状的变异系数在5.66%～26.38%，最大的为主茎分枝，最小的为荚长；将11个形态性状简化成生育期因子、单株荚数因子和粒重因子3个相互独立的主因子，这3个主因子提供了原始性状81.574%的信息；经综合评价优劣排序，来源于唐山本地2个品种排在前两位，来自东北的材料位居最后；经聚类分析，30个小豆品种划分为4大组群，组群的划分与材料的地理来源有密切的联系。指出在育种过程中，应把主茎分枝、单株荚数和生育后期作为首要目标性状进行选择，同时兼顾百粒重、株高等性状，真正选育出综合性状优良的新种质。

Abstract:11 agronomic traits of 30 adzuki bean varieties were evaluated in the present study to provide helpful information for production or breeding.. The results showed abundant of variations among varieties and agronomic traits. The highest co-efficient of variation was observed in number of branches per stem(26.38%), and the lowest was pod length(5.66%).. Further study divided these traits into 3 main factors, namely growth period, pods per plant and seed weight. the 3 factors represented 81.574% information of total traits. Cluster analysis grouped the 30 adzuki bean varieties into 4 populations, which were agreeable to their geographic origins. according to the assessment of 11 traits, two cultivars from Tangshan , HT37 and Tangshanhong, were selected to be further used for production and breeding..
