摘　　要：我国是亚洲栽培稻起源和分化中心之一。稻作历史悠久,稻区分布广泛,类型繁多。经考察和收集,尤其通过国家"七五"、"八五"和"九五"三个五年计划科技攻关协作,编入目录稻种资源75965份,鉴定和繁种67856份入国家种质库保存,获得150余万个性状数据,提供给国家作物种质资源数据库,为今后深入研究和育种利用奠定了丰富的物质基础。本文就我国稻种资源的考察和收集、农艺性状鉴定和编目、繁种与保存、存在问题加以论述,并对今后的稻种资源研究提出一些建议。China is one of the rice origin and evolutional centers in Asia.It has long history on rice cultivation and rich in rice species and ecotypes.Totally 75965 accessions of rice germplasm were collected and catalogued through three Five-Year National Key Pro- grammes implemented from 1985-2000.Of which,67856 accessions were characterized and conserved in National Genebank.A database with more than one and a half millions data on agronomic traits were obtained and stored.This paper presented the general situa- tion on exploration,collection,characterization,catalogue,multiplication and conserva- tion of rice germplasm resources in China.Problems and suggestions on rice germplasm resources in China were also discussed.
