野生稻种质资源安全保存技术

Safety Conservation Technologies for Wild Rice Germplasm Resources

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2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2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中国野生稻资源保存的安全性。

The paper introduces the main methods and technologies for the conservation of wild rice germplasm resources. Wild rice resources conservation adopts 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 exsitu conservation technology systems, in which field genebank, low temperature genebank and in-situ conservation district are complementary. The system greatly improves the security of wild rice resources conservation.
