To explore the interannual variations in the quality of Yunyan series tobacco leaves in the Southern Anhui tobacco growing region, the appearance quality, physical properties, chemical composition, and sensory quality of C2F grade tobacco leaves from the Yunyan series of flue-cured tobacco varieties in the region from 2018 to 2022 were analyzed and evaluated. The results showed that, in terms of appearance quality, color, maturity, body, oil content, color intensity, flexibility, and glossiness generally exhibited an upward trend, with 2020 being the optimal year. Regarding physical characteristics, the single leaf weight gradually improved, essentially achieving a balance between yield and quality. In terms of chemical composition, the nicotine content was relatively low, while the total sugar and reducing sugar contents showed an increasing trend year by year; the total nitrogen content displayed a decreasing trend. For sensory quality, the smoking evaluation scores ranked as 2022 > 2020 > 2019 > 2021 > 2018, with an overall gradual improvement. The quality of tobacco leaves in the study area generally showed a fluctuating upward trend. The next step is to take measures to regulate the physical and chemical properties of tobacco leaves to ensure their long-term stability.
