The evaluation methods for flue-cured tobacco aroma style were summarized in the present paper and the relationships between ecological environment, chemical composition, cultivation, genetic factors and flue-cured tobacco aroma style were investigated. It has been observed that the aroma and its relationship to environmental factors and cultivation technologies were the main areas of current research, while the mechanism of aroma style development and its genetic regulations still need to be speculated. It is suggested that the metabolism and molecular mechanism of aroma formation shall be studied to further explore its developmental pathways and genetic regulation, and the quantitation and standardization of aroma style of specific flue-cured tobacco leaves producing in different areas shall be carried out.
