摘要
甘薯作为重要的粮食、饲料和工业原料,尽管传统育种在甘薯品种选育方面取得了一些成就,但并不能满足当前甘薯产业的需求。随着分子生物学和基因组学的发展,甘薯分子标记的开发利用、高密度遗传图谱的构建、重要性状的QTL定位和全基因组关联分析,均极大程度上解决了甘薯传统育种面临的困难,促进了甘薯育种的速度和效率。本文简要介绍了AFLP标记、RAPD标记、SSR标记、ISSR标记等分子标记在甘薯研究中的应用,就国内外甘薯遗传连锁图谱构建、数量性状QTL定位、甘薯全基因组关联分析研究进展进行了综述,并对甘薯遗传育种研究中功能标记的开发,及深入开展甘薯基因组学、转录组学和蛋白组学相关研究进行了展望。
Sweet potato is an important food,feed and industrial raw material.Although traditional breeding has made some achievements in the selection of sweet potato varieties,it cannot meet the needs of the current sweet potato industry.With the development of molecular biology and genomics,the development and utilization of sweet potato molecular markers,the construction of high-density genetic maps,QTL mapping of important traits and genome-wide association analysis have all promoted the speed and efficiency of sweet potato breeding.This paper briefly introduced the application of AFLP markers,RAPD markers,SSR markers,ISSR markers and other molecular markers in sweet potato research,summarized the research progress of genetic linkage map construction,quantitative trait QTL mapping and whole genome association analysis of sweet potato at home and abroad.The development of functional markers in genetic and breeding research of sweet potato and the further research on genomics,transcriptomics and proteomics of sweet potato were prospected.
