摘　　要：[目的]筛选出高淀粉含量的甘薯新品种。[方法]选择8个淀粉型甘薯新品系进行品比试验,对其农艺性状及淀粉含量进行分析。[结果]品系47208鲜薯产量及淀粉产量均比对照品种徐薯22高,其鲜薯产量比对照高12.64%,淀粉产量比对照高20.35%,该品系结薯性好,可供参加湖南省区域试验;品系41034淀粉产量最高,薯形好,可作为备选品种,再次进行品比试验,进一步验证。[结论]该研究可为高淀粉型甘薯新品系的推广提供科学依据。Objective] To screen the new variety of high-starch sweet potato.[Method] Eight new varieties of starch potatoes were selected for comparative test.The agronomic characters and starch content were analyzed.[Method] Fresh yield of potato line 47208 and its starch yield were both higher than those of the control Xushu 22.Among them, Fresh yield of potato was 12.64% higher than that of control; starch yield was 20.35% higher than that of control.Therefore, line 47208 had the maximum starch yield and good shape, which could be used as alternative va-riety for further comparative test and verification.[Conclusion] This research provides scientific basis for the extension of new high-starch potato line.
