摘　　要：榉属(Zelkova Spach)植物是我国重要的乡土珍贵用材与观赏树种资源。由于长期过度开发等原因,我国榉属植物资源日趋匮乏。文中对我国3种榉属树种的地理分布、生物学特性、利用价值、种群动态与资源状况、遗传改良和良种培育现状及重要意义进行综述,并对其遗传改良与育种研究方向进行展望,以期为我国榉属树种资源的保护与高效利用提供信息与参考。Zelkova Spach are the precious native timber species and ornamental tree resources in China. Due to long-term over-exploitation and other reasons, the Zelkova resources in China have become scarce. In this paper, we review the research progress in the geographic distribution, biological characteristics, utilization value, population dynamics and resources information, genetic improvement and breeding of 3 Zelkova species in China. Moreover, the future research direction of Zelkova species breeding and genetic improvement is prospected. This study will help provide information and reference for the protection and efficient utilization of Zelkova trees resources.
