Abstract: In order to study the growth and adaptability of sweetpotato in the arid or semi-arid regions in InnerMongolia, we chose more than 40 sweetpotato varieties ( lines) with especial usage and screened some new varietiessuitable for growing in local farmlands. The results showed that in Dalateqi region storage root numbers per plant anddry matter content of storage root among the selected sweetpotato varieties ( lines) in test ① reached to 1 % significant level, otherwise protein content reached to 5% significant level. Starch, reducing sugar and soluble sugar content were significant differences among the varieties ( lines) in test ①, however, protein content was no significantdifference. Seen from the correlation coefficients, dry matter content of storage root had significantly negative correlation with reducing sugar and soluble sugar content, and had relative high positive correlation with starch content, butdid not reach to a significant level. Concluded from the test ① and test ②, we totally screened 16 medium or highgeneration sweetpotato materials ( including Xushu 28, Xu 076008, Xu 065922 Xu 060314 and Xu 071419 and soon) , and saved them to pass the winter in the local, and expected to propagate and further screen, as well as demonstration and extend in a large area in the Inner Mongolia region in the next year.
