The results showed that Longzi No.9 had high yield， high quality， high starch and disease resistance， and its comprehensive performance was the most outstanding， so it was suitable to be used as the highquality variety of purple sweet potato in production. The yield of the fresh potato of Quanzishu No.96 and Jinshu No.17 was average， but the yield of starch was high， and the edible quality and appearance quality were both good， so they were suitable to be used as the highquality variety of fresh purple sweet potato in production. The yield of the fresh potato and starch of Longjinshu No.3 at the harvest time was low， but the earlymaturing performance was outstanding， so it was suitable to be used as the earlymaturing variety in production.
