Abstract: Variability of chemical component contents and sensory quality between 2014 and 2018 was statistically analyzed by 350 of flue-cured tobacco samples with grades of B2F and C3F from Huidong county. The results showed that, in average, chemical components of flue-cured tobacco were almost in normal range of high quality flue-cured tobacco, the contents of total sugar and reducing sugar were higher than the average. The variation coefficients of chlorine content and potassium chlorine ratio were the largest, while the variation coefficients of total sugar, reducing sugar and total nitrogen were smaller. There existed obvious variation among chemical components of different grades in different years. The variation coefficients of aroma quality and irritability of flue-cured tobacco in Huidong county were large. The variation coefficients of softness, delicacy, roundness and dryness are low. Smoking sensation of flue-cured tobacco is stable. The variation coefficients of sensory quality of flue-cured tobacco B2F and C3F were larger in 2014 and smaller in 2018.
