摘　　要：选育出了优质高产紫甘薯新品种"烟紫薯3号",进行了紫甘薯食用品质相关性状分析研究。结果表明:烟紫薯3号在国家区域试验和生产试验中平均鲜薯产量分别为29088和21525 kg/hm2,分别较对照宁紫1号增产23.47%和17.22%;其食味总评分为73.3,较对照宁紫1号增加4.74%;紫甘薯食用品质的影响因子按影响程度依次为:花青素含量>还原糖含量>粗蛋白含量>可溶性糖含量>烘干率>淀粉含量>薯肉粘度;花青素含量与食味呈负相关。初步得出:选育食味品质好的紫薯品种必须具有适中的花青素含量、相对较高的还原糖含量、较低的粗蛋白含量、适中的可溶性糖含量、适当偏低的干物率。Bred a new high- yield superior purple sweet potato variety ‘Yanzishu 3＇,analyzed the related traits of edible quality. The results showed that the average fresh yield of‘Yanzishu 3＇was 29088 kg / hm2 and 21525 kg / hm2 in the national regional test and production test,increasing of 23.47% and 17.22% than‘Ningzi 1＇respectively. Total score of taste was 73.3 and compared with control ‘Ningzi 1＇increased 4. 74%. The influence factors of the edible quality of purple sweet potato were followed by the degree was anthocyanin content 〉sugar content 〉protein content〉 soluble sugar content 〉drying rate〉 starch content〉 flesh viscosity. The anthocyanin content was negative correlation to the taste. Showed that a high-quality purple sweet potato variety was necessary to have a moderate anthocyanin content,relatively high reducing sugar content,lower crude protein content,moderate soluble sugar content,and low dry matter content.
