Abstract：Purple-fleshed sweetpotato is rich in anthocyanins and other functional components which are endowed with multiple physiological functions including antioxidation, antimutation, antibacterial activities, hepato-protection, preventing and curing angiocardiopathy. A series of by-products have been developed from purple-fleshed sweetpotatoes both at home and abroad. The breeding and utilization of purple-fleshed sweetpotato are paid extensive attention. In this paper, the research progress on germplasm innovation, genetic characteristics, breeding of purple-fleshed sweetpotatoes in recent years is reviewed and prospects of purple-fleshed sweetpotatoes breeding are discussed.
