摘要:
骨干亲本是新品种培育过程中用到的不可或缺的种质类型,是实现品种升级换代的关键。长期的育种实践表明,主要农作物品种更替与新型骨干亲本的挖掘创制和有效利用具有紧密联系。鉴于骨干亲本对作物育种的重要作用,对主要农作物骨干亲本的研究进展进行概述,期望在骨干亲本所具有的特征、生产贡献和利用价值、形成的遗传基础和创新利用等方面提供参考,并提出了今后的研究方向和重点任务。

Abstract:
Founder parent, which serves as type of the important germplasm resources, plays a pivotal role in update of new varieties. In the view of long-item breeding practices, the update of new varieties is tightly connected with the discovery, development and the effective utilization of founder parents in staple crops. Considering the significant contributions of founder parents in breeding, here we summarize the progress about founder parents in staple crops, which might provide insights on characterization, production contribution and genetic basis for founder parents, and which might propose the research directions and priorities in the future.
Key words:  germplasm  founder parent  breeding  genomics
