摘　　要：[Objective] The research aimed at introducing the background and utilization of germplasm resources in maize.[Method] The research progress on genetic background and utilization of maize germplasm resources was comprehensively reviewed in this paper,including maize heterotic groups and heterotic patterns,their flexible application in breeding and the utilization of various types of original materials.[Result] The results show that germplasm resource is the premise and basis for maize breeding.In-depth understanding and a reasonable selection of germplasm resources can significantly improve the breeding efficiency and speed up the breeding process.At the same time,it is considered that the selection and construction of original materials in maize breeding can not be limited to the heterotic groups and heterotic patterns,but has to be used reasonablely according to different types of germplasm resources and individual breeding objective and idea as well.[Conclusion] This study had broadened the idea and provided inspiration for the maize breeding practice in China.[目的]介绍玉米种质资源的背景及利用现状。[方法]综述了国内外玉米种质资源的遗传背景与利用途径方面的研究进展,包括玉米的杂种优势群及杂优模式,及其在育种中的灵活应用,以及各种类型原始材料的利用方法。[结果]表明种质资源是玉米育种的前提和基础,深入认识和合理选择种质资源,可以显著提高育种效率,加快育种进程。同时认为,在玉米育种原始材料的选择和构建中,不能仅仅局限于杂种优势群和杂种优势模式,还要根据不同类型的种质资源,以及个人的育种目标和思路加以合理利用。[结论]为国内的玉米育种工作开阔思路,提供启示。
