摘要
马铃薯是我国主要粮食作物之一,马铃薯分子育种研究具有重要意义。在二倍体马铃薯中,重要性状控制基因的QTL定位及克隆已经有大量报道。近年,随着同源四倍体分析软件的开发,四倍体马铃薯的遗传图谱构建和QTL定位也取得了突破性进展。分子标记是马铃薯育种的重要辅助手段,可快速准确筛选出多个优良性状。对马铃薯重要农艺性状的QTL定位和克隆,以及3个抗病性状分子标记辅助选育的研究进展进行概述,为加快马铃薯分子育种研究提供参考和实践依据。
Potato is one of the main food crops in China,and research on potato molecular breeding research is of great significance.In the diploid potato,QTL mapping and cloning of important genes has been reported extensively; The development of tetraploid linked analysis software,genetic map construction in tetraploid potato and QTL mapping have also made breakthrough progress in recent years.Meanwhile,molecular markers are an important supplement method for potato breeding and it can quickly and accurately screen out multiple good traits.In this paper,the progress of the QTL mapping,cloning of important agronomic traits in potato and 3resistance traits linkage markers breeding were summarized,to provid a reference and practical basis for accelerating potato molecular breeding.
