摘　　要：多酚是在植物性食物中发现的、具有潜在促进健康作用的化合物。为筛选高多酚含量且稳定性好的甘薯品种,测定了5个产地21个甘薯品种（系）的多酚含量,分析了其基因型差异和环境效应及其稳定性。结果表明：甘薯多酚平均含量为0.485 g/100 g,品种间变幅为0.302~1.092 g/100 g,变异系数为34.41%;产地间变幅为0.201~1.337 g/100 g,变异系数为46.98%,基因型、产地以及基因型与产地互作效应均达极显著水平,显示甘薯多酚含量受基因型、产地以及基因型与产地互作效应的影响。同时筛选出＂金山1222＂、＂浙大9201＂、＂浙34-81＂、＂浙255＂、＂徐55-2＂等多个多酚含量高、产地稳定性强的品种。The polyphenol contents of 21 sweetpotato varieties grown at 5 locations were determined in order to select sweetpotato varieties with high ployphenol content.Results： The average polyphenol content of the 21 genotypes is 0.485 g/100 g,with a range from 0.302 g/100 g to 1.092 g/100 g and with a CV of 34.41%.The range of polyphenol content among the 5 locations is from 0.201 g/100 g to 1.337 g/100 g and with a CV of 46.98 %.So the polyphenol content in sweetpotato is affected with genotype,location,as well as their interaction.Some sweetpotato varieties with high polyphenol content and high location stability,such as Jinshan1222,Zheda9201,Zhe34-81,Zhe255,Xu55-2,are identified.
