摘 要 ：V.minima是豇豆属中的野生种，国内研究报道较少。本研究对搜集到的V.minima野生资源的地理分布、原生境主要性状及其与野生小豆、栽培小豆性状间的差异进行了分析。结果表明：（1）搜集到的45份V.minima野生资源来源于辽宁、天津、河北、山东和北京等省市，资源在粒色、籽粒大小、植株形态等方面变异丰富。（2）与栽培小豆相比，V.minima株型大，上胚轴短，叶片小，荚果细短，炸荚性强，荚色深，籽粒小，粒色多样。植株与籽粒性状与野生小豆相近，但种脐突出明显，且种脐长。（3）聚类分析将V.minima与野生小豆分为一类，而与栽培小豆明显分开。

Abstract:V.minima is one of the important Vigna species in legumes. However, there was little research report about it. In this paper, the geographic distribution and characteristics about V.minima were elucidated and the differences among V.minima with V.angularis and V. angularis var. nipponensis were analysed.The results showed that (1) Forty-five V.minima resources were collected from Liaoning, Tianjin, Hebei, Shandong and Beijing. Germplasm collected indicated rich variation in seed color, seed size and plant type，etc. (2) Compared with V.angularis, V.minima showed such characters as big plant, short epicotyls, small leaves, slim and short pod, strong shattering of pod, blackish brown pod, small seed and colorful seed coat. Compared with V. angularis var. nipponensis, the traits of plant and seed were similar, but its hilum was prominently protruding and longer. (3) By cluster analysis, V.minima was clarified into the same group with V. angularis var. nipponensis, and was distinct separated with V.angularis.
