摘　　要：测序扩增区段(SCAR)标记是基于PCR技术的单基因位点多态性标记,相对其他分子标记,他具有开发成本低,稳定性高,单位点多态等特点,近10年内被广泛用于分子标记辅助选择、抗病(虫)基因连锁定位、高密度遗传图谱构建、种质纯度及品种鉴别等方面。回顾了近几年国内外关于SCAR标记的研究进展,应加强SCAR标记在牧草品种选育(尤其是抗病虫、抗逆),鉴定和种质评价方面的研究。Sequence characterized amplified region （SCAR） is a new molecular single-site markers based on PCR. Compared with other markers, it has such merit as low price,high stability, site-specific and so on. It has been applied in molecular assisted selection, linkage analysis, precisely location of target gene, discriminate in cuhivars and so on in recent years. After brief review on recent development of SCAR on plant,it was suggested that research should be enhanced on application of SCAR in grass for such purpose as molecular assisted selection, variety evaluation.
