我国作物种质资源保存研究与展望

我国于１９８４年１９８６年在北京建成两座国家种质库，９０年代初又在青海建立一座复份库，形成了国家库中，长期配套和异地结合的种质资源保存体系。截止１９９３年底，国家库保存种质资源达２７万余份，到１９９５年保存总数将达到３０余万份。与种子入库时，在国家库的管理，种子质量检测，种子干燥以及低温保存技术研究等方面取得一定进展，今后将继续扩大种质贮存、加强贮存种子生活力跟踪监测，无破坏性检测技术，贮存生理和

Conservation research and prospects of crop germplasm resources of China

wo national genebanks were set up successively in 1984 and 1986,in the early 1990s,a duplicate genebank was established in Qinghai Province,China,thus,the system forconservation of germplasm resources in the national genebank was formed,which can be long-term, medium-term integrated and combined in different places.By the end of 1993,the germplasm resources in national genebank was over 270 thousand accessions,the total amount of conservated resources would be reached 300 thousand accessions by 1995.Some progresses have been made in the management of information,quality inspectation and dry of seeds and other techniques for conservation under low temperature condition etc. It needs further strengthening the research on seed viability inspectation,the undestructive seed test technique to the physiology,biochemistry and genetics of seed conservation,ultradry conservation and core collection besides enlarging the capacity of the genebank.
