野生稻种质资源安全保存技术

本文介绍了野生稻种质资源保存的主要方法与技术及特点。野生稻资源保存采用原位保存与异位保存两种方式。原位保存也称原生境保存，通过在原生地建立保护区（点）保护资源；异位保存是对野生稻资源采取异地保存的一种方式，包括种质圃保存和种质库保存两种方法。原位与异位相结合，种质库、种质圃与原生境保护区（点）相补充的保存技术体系大大提高了我国野生稻资源保存的安全性。

Safety Conservation Technologies for Wild rice Germplasm Resources

The paper introduces the main methods and technologies for the conservation of wild rice germplasm resources.Wild rice resources conservation adopt two ways,in situ and ex situ conservation.In situ conservation is to establish conservation district in the original region;ex situ conservation is to preserve wild rice in non-original places,including field genebank and low temperature genebank.China has established in situ and ex sute conservation technology systems,in which field geneband ,low temperature genebank and in situ conservation district are complementary.The system grately improves the security of wild rice resources conservation.
