摘要
Abstract
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.关键词
