In order to study the effect of salicylic acid on drought resistance of foxtail millet during germination period, the seeds of Henggu 15, Henggu 13, Jigu 19 and Hengsi No.1 were soaked in salicylic acid for 24 h with 18%peg to simulate drought environment. The germination rate, germination index, vigor index, root length, seedling height and fresh weight of the four foxtail millet were determined. The results showed that under drought stress, all varieties showed different performance after soaking in salicylic acid, and the drought resistance of some varieties did not change significantly. The germination ability of Jigu 19 and Henggu 15 increased significantly, and the vigor index of Henggu 15, Jigu 19 and Henggu 13 increased significantly. 0.6 mmol/L salicylic acid was the optimal concentration for soaking seeds. According to the comprehensive analysis of membership function, the drought resistance of four millet varieties after soaking with salicylic acid was Henggu 13 ＞ Jigu 19 ＞ Hengsi No 1 ＞ Henggu 15.
