作物种质资源保存在我国已取得迅速发展。近１０年来，种质资源保存体系已初步形成，建成了长期种质库２座，中期种质库１０余座：国家种质库长期贮存上百种作物２４万余份种质，隶属２９科，１６４属，４７０多个种（亚种）；在９３个国家种质圃中，保存多年生和无性繁殖作物２万余份种质。在种质保存技术研究方面也取得重要进展。

Preservation of crop germ-plasm resources has developed rapidly in China. In the last decade a system of preservation was established. Two long-term and more than ten mediumterm storage facilities for germ-plasm preservation have been built. More than 240 000 germplasms of 100 kinds of crops, including 29 families, 164 genera and more than 470 species (subspecies) are long stored in the National Genus Bank of the Chinese Academy of Agricultural Science. More than 20 000 germ-plasms of perennial and vegetative crops are preserved in 23 National Germ-plasm Nursery. At the same time, the methods used for the preservation of germ-plasm have also been improved.
