摘　　要：甘薯是世界上重要的粮食和工业原料作物,它的起源与进化历程一直是科学家们十分关注的话题.由于甘薯具有自交不亲和性,且基因组复杂的特性,甘薯的遗传理论研究远落后于其他作物.甘薯的近缘野生种含有较多优良性状,故研究甘薯及其近缘野生种的起源进化,有利于发掘甘薯优良种质资源,促进育种工作.从形态学特征、细胞遗传学特征、分子标记、基因组信息等方面综述甘薯及其近缘野生种起源与进化的研究进展.Sweetpotato is an important food and industrial raw crop worldwide,and its origin and evolutionary have been a topic of concern to scientists.Theoretical study on genetic of sweetpotato lags far behind other crops due to its self-incompatibility and complex genome.The relative wild species of sweetpotato contain many excellent traits,so exploration of the origin and evolution of sweetpotato and its close wild species is beneficial to tap the superior germplasm resources and promote sweetpotatao breeding.The progress of research on the origin and evolution of sweetpotato and its closely related wild species is reviewed based on morphological characters,cytogenetic characters,molecular markers,and genomic information.
