Abstract: The total sugar content of flue-cured tobacco from main tobacco-growing areas in Xiangxi were determined by continuous flow method to study its regional characteristic. The results show that the mean of total sugar content in the flue-cured tobacco leaf of B2F,C3F and X2F grade were 24.54%,32.28%,32.41%,respectively, and .belong to better-sugar tobacco- planting areas. The sequence of total sugar content: X2F>C3F>B2F. There were extreme significance difference in the total sugar content of flue-cured tobacco among grades and among counties; and significance difference among varieties and among elevation in X2F grade; and not-significance difference among soil types. The total sugar content creased gradually from the low total sugar content areas of southeast to west and northeast orientation.
