花生分子标记的研究进展

国内外对花生的研究特别是在分子水平上的研究相对水稻、油菜等农作物比较薄弱。近些年，分子标记技术迅速发展，在花生上也得到广泛的应用。本文从花生属起源、种质资源的遗传多样性、抗性基因的标记和指纹图谱等方面，综述了国内外花生分子标记的研究进展。

Molecular Marker Techniques and Their Application in peanut(Arachis hypogaea L. )

Peanut (Arachis hypogaea L.) is an important oilseed and cash crop in the world. It is an important source of vegetable oil and protein in certain developing countries . China is the largest country in terms of peanut production, consumption and export trade. But comparative to rice and rape, it was short of studies in peanut (Arachis hypogaea L.), especially in molecular lever. In the resent years, molecular marker based on DNA developed promptly, and it was widely used in peanut. Application of molecular marker techniques were reviewed in this paper worldwide in origin of peanut, genetic diversity of germplasm resources, gene of resistance to disease and fingerprint in peanut.
