摘　　要：大豆在中国已有5000多年的栽培历史。至2000年底,中国已经保存国内外25144份栽培大豆资源,是世界上保存栽培大豆品种数量最多的国家。本文针对大豆品种资源在国家中期库保存的种子数量少、种子生活力差和特性鉴定内容有限的现状,提出更新与鉴定、研究和应用相结合的策略以及在保证种质安全性、品种特性和田间试验准确性方面采取必要的技术措施,以确保种质的安全更新。Soybean originates in China and has been cultivating for more than 5000 years.Right now there are more than 20 thousands Chinese cultivated soybean stored in the national Genebank for longterm storage,which has the largest cultivated soybean col- lection in the world.The duplicated collection set is stored in the national midterm stor- age,but the seeds weight and germinating rate are decreasing as well as limited characters of these varieties are identified.The regeneration strategy is suggested,which is combina- tion of regeneration and identification,regeneration and study,regeneration and applica- tion,in order to better characterizing the soybean germplasm.Meanwhile,technical mea- surement should be adopted in securing seeds safety,variety characters and data accuracy, when soybean germplasm are regenerated.Then,the soybean germplasm can be widely used by having enough seeds and detail technical informatio
