In order to screen new varieties of flue-cured tobacco suitable for the ecological environment of Xunyi tobacco area, and to provide a basis for the production and utilization of high-quality tobacco leaves, we used Qinyan 99 as the control in 2022, which was the main cultivar in Xunyi tobacco growing area. The differences in field growth period, botanical properties, agronomic properties, field natural incidence rate, economic properties, conventional chemical composition content, appearance quality and sensory quality of flue-cured tobacco were compared among Qinyan 99, Qinyan 96, Qinyan 201, Zhongyan 100, Yuyan 13 and Y2001. Results showed that there was little difference in the growth period among different tobacco varieties, ranging from 142 to 155 days; Qinyan 96 and Y2001 had strong growth potential in the field, strong disease resistance, high yield, output value and the proportion of medium to high grade tobacco. They had excellent appearance and sensory quality, and good coordination of chemical components, which could be used as reserve varieties for promotion and planting in Xunyi tobacco area.
