中文摘要:

      谷子是我国传统粮食作物, 具有抗旱、耐瘠薄、营养价值高等优点, 谷子的种质资源分析及育种研究非常重要, 随着分子生物学的发展, 分子标记技术的出现为谷子的遗传研究及育种开辟了新的思路和手段。分子标记包括DNA分子标记和蛋白质分子标记, 其中DNA分子标记常被用于构建遗传连锁图谱、基因定位及QTL分析、遗传多样性研究、系谱分析与品种鉴定和比较基因组研究等, 本文分别介绍了谷子常用的DNA分子标记和蛋白质分子标记及其特点, 并综述了其在谷子上的研究应用情况, 简要分析和展望了分子标记在谷子上的未来发展。

英文摘要:

      Millet is a kind of traditional food crop in China, which has the advantages of drought resistance, barren tolerance, and high nutritional value. The analysis of germplasm resources and breeding research of millet are very important. With the development of molecular biology, the emergence of molecular marker technology is the genetic research and breeding of millet open up new ideas and means. Molecular markers include DNA molecular markers and protein molecular markers. Between them, DNA molecular markers are often used to construct genetic linkage maps, gene mapping and QTL analysis, genetic diversity research, pedigree analysis and variety identification, and comparative genome research, etc. This paper reviewed DNA molecular markers and protein molecular markers commonly used in millet and their characteristics, respectively, summarized their research and application on millet, and briefly analyzed and prospected the future development of molecular markers on millet.
