分子标记技术在大豆遗传育种中的应用

Applications of Molecular Marker in the Soybean Genetic Breeding

大豆是世界上重要的经济与粮食作物,大豆研究一直受到人们的广泛关注,但与玉米、水稻等作物相比,其研究进展十分缓慢。20世纪80年代末,DNA分子标记技术的出现,大大提高了遗传育种效率。本文从大豆遗传图谱的构建、遗传多样性研究、数量性状基因分析、分子标记辅助育种等四个方面概述了分子标记技术在大豆遗传育种中的应用情况。

As soybean is the most important economic and food crops in the world,soybean research has been paid more attention at all times,but soybean researches progressed slowly comparing with corn,rice and other crops.The emergence of DNA molecular marker technology in late 1980s greatly improved the efficiency of genetic breeding.Molecular markers applied in soybean genetics and breeding were summarized from the four aspects,i.e.,soybean genetic map construction,genetic diversity studies,genetic analysis of quantitative traits, and molecular marker-assisted breeding.
