摘　　要：谷子是一种重要的杂粮作物。谷子是二倍体自花授粉作物,基因组较小,与水稻基因组存在明显的共线性,是开展基因组研究的理想模式植物。SSR标记具有共显性、多态性高、操作简单等优点,广泛应用于遗传多样性研究、品种鉴定、遗传图谱构建、功能基因研究、分子标记辅助选择育种等领域。本文对谷子SSR标记的开发和应用进行总结,提出了谷子分子遗传研究中存在的问题,并对今后的发展趋势作了初步探讨,旨在为谷子分子遗传研究提供参考。Foxtail millet is an important minor cereal crop. Genetictraits such as self - pollination, diploidy, and small genome size which is close to the rice genome make it an ideal model plant for genome research. SSR markers have been proven to be useful in molecular biology studies because of its high polymorphism,codominant and convenience. SSR markers were widely used in such areas as genetic diversity, cultivar identification, genetic map construction ,functional gene study, and molecular marker -assisted selection. In this paper, the progress in isolation and application of SSR markers in foxtail millet were reviewed, the problem and future development were also discussed, for the purpose of providing reference for molecular genetic studies in foxtail millet.
