基于连锁不平衡的关联分析已在玉米基因组学研究领域取得了显著进展。随着玉米自交系B73全基因组序列的测定、玉米单体型图的绘制、高密度分子标记的开发及控制玉米重要性状基因的克隆,玉米分子育种与品种分子设计工作将会得到快速发展。介绍了玉米基因组概况、玉米关联分析研究现状、玉米分子育种与品种分子设计的研究进展与发展态势。 Correlation analysis based on linkage disequilibrium has made significant progress in maize genomics research. With the determination of whole genome sequence of maize inbred line B73, the development of maize haplotype map, development of high-density molecular markers and cloning of maize important traits, molecular breeding of maize and molecular design will be rapidly developed. This paper introduced the general situation of maize genome, current research status of maize association analysis, research progress and development of maize molecular breeding and molecular design.
