摘要:
2016-2018年“第三次全国农作物种质资源普查与收集行动”广东调查队收集到广东57个县(市、区)的甘薯地方品种资源201份。调查发现,广东甘薯地方品种资源集中分布在粤北、粤东和珠三角交接片区,从揭阳揭西县、广州从化区和阳江阳西县收集最多。收集调查和表型鉴定的结果表明,收集的甘薯地方品种主要以鲜食型的品种为主。鉴定评价获得高产资源76份,高干物率资源29份。综合表型性状筛选出石牌红甘茨、一点红、鸡骨香、黄沙高山红薯和石角红薯等5份高产、优质和食味优的甘薯地方品种资源。

Abstract:
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.
Key words:  sweetpotato landraces  germplasm resource  survey and collection  identification and evaluation
