国家作物种质库资源长期安全保存进展

Progress on Long-Term Safe Conservation of Crop Germplasm Resources at National Grop Genebank

种质资源是支撑作物新品种培育和农业科技原始创新的基石,其收集与保存是保障粮食安全的根本。我国一直十分重视作物种质资源长期安全保存与共享利用,我国的作物种质资源长期保存设施建设和技术研发均取得了显著进展,保障了国家战略资源的安全。本文系统总结国家作物种质库资源长期保存发展历程,以及所保存的资源在科技创新和新品种培育中发挥的重要作用,以期为种质资源的保护与利用提供借鉴。

Crop germplasm resources(CGRs) are the cornerstone to support new crop breeding and the original innovation of agricultural science and technology. The collection and conservation of CGRs is the fundamental basis for food security. The Chinese government has always attached great importance to the long-term safe conservation and sharing of CGRs, and remarkable development has been made in the construction of conservation facilities and development of technologies,ensuring the safety of national strategic resources. In this article, we summarizes the long-term conservation and development process at National Crop Genebank(NCGB),and the important role of CGRs in scientific and technological innovation and new variety cultivation, in order to provide useful reference for the conservation and utilization of germplasm resources.
