摘　　要：针对目前美人蕉属品种分类系统繁多、分类标准各异、不利于国际交流的现状,根据《国际栽培植物命名法规》(ICNCP)建立美人蕉属品种分类新系统。首先根据花冠、瓣化雄蕊和叶片的形态特征划分种系,再按株高划分品种群,最后根据叶色、花色、花型、花径等的差异划分品种。照此系统从品种起源、种系形态特征和品种群的园林应用特点等方面对收集的66份国内外美人蕉种质进行分类。结果表明,这些种质被分为5种、6品种群及66个品种。The existing various canna cultivars classification systems varying in criterion, make many disadvantages in international business. A new classification system was proposed based on the ICNCP. The morphological characteristics of petal, staminodes and folia were considered as the prerequisite criterion in species classification. Using height as the second degree criterion in groups classification. Comor of leaf and flower, size and shape of flower were used in cultivars classification. According to this system, 66 individuals were divided into 5 species or hybrids, 6 cultivar-groups, 66 cultivars. The three-degree system is simple and effective, measuring up with international routine. It can not only reflect the morphological characteristics of species and cultivar-groups, the origin of cultivars, but also point out the special purpose of every group in landscape design.
