摘　　要：为了解我国甘薯登记品种的现状,对2018—2023年甘薯登记品种的基本信息、选育方式、种植区域、登记主体、抗病性、品质、产量等进行了分析。结果表明,我国共登记甘薯品种430个,平均每年登记71.67个,2020年登记品种数量最多,2021年登记品种数量最少;育成品种类型丰富,鲜食类最多;定向杂交、集团杂交、放任授粉是育成品种主要的育种方法;长江中下游薯区可适宜推广种植的品种最多,累计为228个,占登记品种的53.02%;共有92个主体进行了品种登记申请,科研院所登记的数量最多;登记品种整体上抗病性较好;除甘薯品种的淀粉率整体呈上升趋势外,粗蛋白、还原糖、可溶糖、花青素和胡萝卜素含量整体均呈下降趋势;鲜薯、薯干和淀粉的平均产量均呈现下降的趋势。In order to understand the current situation of registered varieties of sweet potato in China,the basic information,breeding method,planting area,registration subject,disease resistance,quality and yield of registered varieties from 2018 to 2023 were analyzed.The results showed that a total of 430 sweet potato varieties were registered in China,with an average of 71.67 per year.The most varieties were registered in 2020 and the least in 2021.The cultivated varieties are rich,and the fresh sweet potato is the most.Directional crossing,group crossing and free pollination are the main breeding methods for varieties.The number of varieties suitable for popularization in the middle and lower reaches of the Yangtze River is the largest,with a total of 228 varieties,accounting for 53.02%of the registered varieties.A total of 92 subjects applied for variety registration,and the research institutes registered the most.The registered varieties had good disease resistance on the whole.The contents of crude protein,reducing sugar,soluble sugar,anthocyanin and carotene showed a decreasing trend except for the increasing trend of starch content.The average yield of fresh potato,dried potato and starch showed a downward trend.
