选用优质食用、特用等11个甘薯新品系，通过在内蒙古达拉特旗进行异地鉴定，以研究甘薯在干旱、半干旱地区的适应性，结果表明：鲜薯和薯干产量在品种间的差异分别达到显著和极显著水平，在品种与地点互作间的差异未达显著水平；薯块干率、可溶性糖含量在品种间的差异分别达到极显著和显著水平，淀粉含量、还原糖含量和粗蛋白含量在品种间的差异未达到显著水平，这5个品质性状在品种与地点互作间的差异均达极显著水平。其中，综合性状较好的3个优质、高产新品种为徐5919、食5和徐1021等，可在内蒙古等干旱、半干旱地区大面积推广。

To research the adaptability of sweet potato in arid area and semi -arid areas, we selected 11 sweet potato cultivars or clones for edible use or special use to plant in Dalateqi of Inner Mongolia .The results showed that the differences in potato tuber fresh weight and dry weight among varieties reached a significant or very significant level , but the differences in potato tuber fresh weight and dry weight between variety ×location interaction did not reach a significant level .The differences in tuber dry matter content and soluble sugar content among varieties reached a significant or very significant level , while the differences in tuber starch content, reducing sugar content and crude protein content among varieties did not reach a significant level .The differences in these five quality traits between variety ×location interaction all reached a very significant level .We finally screened out 3 good-quality and high-yielding sweet potato new varieties with better comprehensive characters (including Xu 5919, Shi 5, and Xu 1021), and expected to demonstrate and extend them in the large arid and semi -arid areas of Inner Mongolia in the future .
