[Objective] The research aimed to explore new varieties of sorghum suitable for popularization and application in the northern mountainous area of Chengde. [Method] The comparative experiments on 10 introduced new varieties of sorghum were carried out to determine the disease resistance, high yield and suitability of each variety in the precocious area of Chengde. [Result] The results showed that the frost-free period suitable for Aoza 1 and Chihe 851 in the north of Weichang County was about 120 d, and the next year could be popularized in a large area. The Jizh 118 could be planted in a small area in a region with low light and heat in low altitude . Chishu 28 and Chishu 29 could be planted in northern part of Longhua, which had a frost-free period of 125 days. Chishu 24 was planted in southern part of Longhua to cover the plastic film. Ji’gu 122, Ji’gu 124 and Jishu 130 had longer growth period and were suitable for Chengde Southern planting. [Conclusion] The results provided references for the sorghum production in Chengde area.
