简要介绍了玉米基因组学发展背景，概述了玉米基因组学研究进展。在结构基因组学方面，新发展的DNA编码序列富集与过滤技术大大推动了玉米基因组学测序工作的进展，目前已获得基因组中80%的编码序列。功能基因组学在EST计划、Mu-tagging技术、芯片技术和TILLIING技术的推动下也取得了长足的进展。与水稻和拟南芥等的比较基因组学，有助于解读基因组序列，推测未知基因的功能，并促进了基因作图。生物信息学则积累了海量的数据库并呈指数增加，新软件开发、数据的解读和图谱的整合是其重要的研究方向。讨论了基因组学发展对玉米育种的影响。

The background and progress of the maize genomics was introduced and summarized. More than 80% of encoding sequences in maize genome had been sequenced as the great progress in structural genomics due to enriching and filtration methodology of encoding sequences which were developed recently. Functional genomics was also promoted great forward with the promoting of the EST project, Mu-tagging, microarry technology and TILLING strategy. Meanwhile, the comparative genomics with deciphered sequences and data from Aribidopsis and rice genome facilitate to decode the sequences, to deduce their function, and to aid the mapping. Exponentially accumulating data, newly developed softwares, sequence deciphering were the key subjects in bioinformatics nowdays. The impact of the genomics on corn breeding was dicussed too.
