摘　　要：榛子为榛科榛属植物,全世界有16种,我国原产8个种和2个变种;我国现有榛林的95%是野生平榛,选育的平欧杂种榛和引进的欧洲榛是目前主要的栽培种。从平榛资源调查和选优、平欧杂种榛种质创新和品种选育、我国其他榛属资源的利用和国外榛属资源的引种等方面对我国榛子的育种现状进行了介绍;对我国及国外榛属植物种质资源的研究进展进行了总结,对比了我国与世界先进水平的差距;并从现有平欧杂种榛在科研和生产中亟待解决的问题、第1代平欧杂种榛的目标性状改良及今后榛属植物的育种策略等方面,对榛属育种与资源利用提出了一些见解,以期与国内同行专家进行交流。The genus Corylus is a member of the Corylaceae family of the order Fagales.There are about 16 species around the world,and among these species,8 species and 2 subspecies are originated in China.Ping hazelnut（Corylus heterophylla Fisch.） is a specific wild species native to China,distributed in the broad region in northern China.The selected Ping＇ou hybrid hazelnuts（C.heterophylla Fisch.× C.avellana L.） and the introduced European hazelnut（C.avellana） are the main cultivars cultivated in China.In this review,we introduce the investigation and the selection of Ping hazelnut,the hybridization and the selection of Ping＇ou hybrid hazelnuts,the utilization of the other species native to China and the introduction of the germplasm resources overseas.The research progresses on the germplasm of Corylaceae worldwide are summarized and the gap between domestic and overseas is also discussed.Finally,several personal opinions are proposed on some burning questions,such as the research and production of Ping＇ou hybrid hazelnuts,the breeding strategies of the trait improvement for the first generation of Ping＇ou hybrid hazelnuts and utilization of the germplasm resources of Corylaceae.We hope to exchange opinions with experts in this field.
