我国核桃育种的回顾和展望

Retrospect and Prospect of Walnut Breeding in China

对我国核桃的育种研究工作作了较系统的回顾,包括种质资源、实生选育种、杂交育种、引种研究、遗传规律、生物技术等方面。我国核桃品种和种质资源丰富、栽培面积大,是世界上核桃栽培面积最大、产量最多的国家。在以后的核桃育种研究工作中,应充分发挥乡土资源丰富的优势,继续加强核桃的实生选种的研究。利用不同地理类型及品种特性开展核桃的杂交育种研究,利用生物技术开展核桃种质的鉴别、保存及抗病抗虫新品种的选育。

The research of walnut breeding in China is reviewed systematically. There are rich resource of variety and germ plasm in China, and the cultivation areas and yield are premier on the world. In the coming research, we should take advantage of local rich resource, continue to study the selection of seedling, carry out cross-breeding making use of different geography type and varieties characteristics, carry out appraisement and conservation of germ plasm, and carry out selection and breeding of anti-pest and anti-disease variety.
