Abstract: 【Objective】 To understand the performance of sweet sorghum germplasm resources in different planting areas and to provide reference for breeding sweet sorghum varieties in Xinjiang Region. 【Method】 The comparison tests for Liaotian No. 15-1, Liaotian No. 13, Liaotian No. 1, Liaotian No. 3 different varieties of sweet sorghum were performed in Manasi County and Qitai County, Xinjiang and the effects of different planting areas on agronomic traits and nutritional components of different cultivars were analyzed. 【Result】 The results showed that all varieties planted in Manasi were basically shorter than those planted in Qitai, among them Liaotian No. 1 had the shortest growth period of 138 days. The biological yield of Liaotian No.15-1 in Manasi and Qitai were the highest, which were 15.94 t/hm² and 14.88 t/hm² , respectively. The total sugar contents of Liaotian No.1 in the two areas were the highest, which were 9.15% and 8.39%, respectively. The crude protein contents of different sweet sorghum stalks had little differences. The crude protein content of Liaotian No. 13 was the highest, which was 6.41%. The different regions had great influence on the content of total sugar, reducing sugar and crude cellulose content of the same sweet sorghum varieties, and the difference between the two places was very significant. 【Conclusion】 In general, the yield and nutrients of different varieties were higher in Manasi than in Qitai. Liaotian 15-1 has the highest biological yield and the quality of total sugar and crude protein content are also good, so it can be preliminarily judged that the variety is suitable for planting and popularizing in the local and nearby areas.
