区域性优质核桃种质资源保存技术

Conservation Technology of Regional High Quality Walnut Germplasm Resources

通过采集区域性优质核桃母树穗条,采取核桃大树高桩嫁接的方式进行资源收集保存,总结出一套优质核桃种质资源保存技术,包括采穗母树选择与处理、穗条采集与处理、砧木选择与处理、嫁接、接后管理、病虫害防治、后期综合管理及建立技术档案等全过程,以期实现对优质核桃资源的有效保护,满足今后基地品种改良、资源延续及大力发展核桃产业的需要,为建立优质核桃资源基因活体库和开展核桃遗传科学研究奠定基础。

By collecting regional high quality walnut mother tree scions,we collected and preserved the germplasm resources of high quality walnut by high pile grafting walnut tall trees,a set of high quality walnut germplasm resources conservation technology were summarized,including the selection and treatment of mother trees,the collection and treatment of scions,selection and treatment of rootstocks,grafting,management after grafting,diseases and insect pests control,comprehensive management in the later stage and the establishment of technical files,etc.,in order to achieve effective protection of high quality walnut resources,meet the needs of future varieties improvement,resource continuation and vigorous development of the walnut industry,lay the foundation for the establishment of a living gene bank of high quality walnut resources and the research of walnut genetic science.
