The 467 flue-cured tobacco samples from 19 provinces were tested and analyzed. The results indicated that the tar content and chemical component of flue-cured tobacco leaf varied with the positions. The tar content was closely correlated with the chemical component. For upper leaves, cutters and lugs, the tar content was highly significantly and negatively correlated with total sugar and reducing sugar, highly significantly and positively correlated with total nitrogen, nicotine, petroleum ether extract and total volatile alkaloid.
