Under the frame of the Third National Survey and Collection Action on Crop Germplasm Resources, 201 sweetpotato landraces were collected from 57 counties in Guangdong province from 2016 to 2018. These sweetpotato landraces were mainly distributed in the junction areas of northern Guangdong, eastern Guangdong and Pearl River Delta, and most of them were found from counties including Jiexi, Conghua and Yangxi. Analysis of the phenotypic variations showed that, a majority of the landraces were qualified for fresh-edible sweetpotato varieties. These elite landraces including 76 high-yield and 29 high-dry-matter-content sweetpotato landraces have been identified. Especially, five sweetpotato landraces with high yield, good quality, and excellent taste have been clarified, including Shipai hong ganci, Yidianhong, Jiguxiang, Huangsha gaoshan hongshu, and Shijiao hongshu.
