摘　　要：通过对湖南省核桃遗传资源调查研究,旨在摸清家底,为资源的保护和合理开发利用提供参考资料。调查结果表明:湖南省核桃资源有3属5种,1变种,2引进种,主要分布在湘西地区,核桃(泡核桃)以房前屋后,零星栽培为主,湖南山核桃多为野生半野生的纯林,浙江山核桃和薄壳山核桃出现了商业化栽培的示范基地。筛选了核桃样品71份,分析了其果实的主要特性,甄别特异种质资源6类。根据资源特点和利用现状,提出了湖南省核桃资源开发利用前景和保护策略。To find out the resource distribution of walnut and hickory,provide reference materials for resource protection and rational development and utilization,this study investigated the genetic resources of walnut and hickory in Hunan Province,China.The results showed that:there are 3 genera and 5 species,1 variety and 2 introduced species of walnut and hickory resources in Hunan Province,which mainly distributed in western Hunan Province.Walnut is sporadically cultivated around house.C.hunnanensis is found in mostly wild and semi-wild pure forests,while C.cathayensis and C.illinoensis appears in commercial cultivation.71 samples were screened,the main characteristics of fruit were analyzed,and 6 types of special germplasm resources were identified.According to the characteristics and utilization status of resources,the development and utilization prospect and protection strategy of walnut and hickory resources in Hunan Province were put forward.
