The invention discloses a tobacco composition in flue-cured type cigarettes. The tobacco composition comprises the following tobaccos in parts by weight: 2-3 parts of third-grade tobacco in the central Hubei Enshi with the sugar-nicotine ratio of 8-12, 1-2 parts of first-grade tobacco in the north Yunnan Pu'er with the sugar-nicotine ratio of 8-12, 1-2 parts of third-grade tobacco in the central Gangxi Hezhou with the sugar-nicotine ratio of 8-12, and 1-2 parts of second-grade tobacco in the central Guizhou Tongren with the sugar-nicotine ratio of 8-12. The tobacco composition can be used forcompletely replacing the Canada tobacco used in the existing first-grade and second-grade cigarettes, thereby effectively relieving the dependence of the cigarette product development on the importedtobaccos, improving the utilization efficiency of the domestic tobaccos, and ensuring the sustainable development capability of cigarette products. The first-grade and second-grade cigarettes prepared by using the tobacco composition provided by the invention to replace the Canada tobacco used in the existing first-grade and second-grade cigarettes can still satisfy the style characteristic requirements of the first-grade and second-grade cigarettes.
