<正>生物技术的发展给植物遗传育种研究带来了巨大的变化 ,DNA分子标记技术的应用是其中最显著的变化之一。遗传育种是花卉业发展的重要基础 ,也是技术创新最活跃的分支。笔者从分子遗传图谱的构建、亲缘关系分析、农艺性状定位、标记辅助选择等 4个方面阐述了分子标记在花卉育种研究中的应用

Great changes in the study of plant genetic breeding had been brought about by the development of biotechnology,and the application of DNA molecular marker technique is one of the most significant changes.Genetic breeding is an important base for the development of flower plant industry and also is one of the most active branches in technical innovation.The application of molecular marker in the study of flower plants genetic breeding such as construction of molecular genetic map,analysis of relationship,location of ornamental characters and marker assisted selection is described in this paper.
