Regional Characteristic Analysis of Chemical Components and Sensory Quality of Hongda Tobacco in Yunnan Province

Purpose The aim was to analyze the regional characteristics of chemical component and sensory quality of Hongda tobacco in Yunnan Province, and provide references for planting plan, adjustment of cultivation techniques and choice of raw materials of Hongda tobacco.Method Hongda C3F tobacco was chosen from eight counties in Kunming, Yuxi, Qujing and Dali. The chemical composition was analyzed using variance analysis and multiple comparisons. Meanwhile, the regional characteristics of chemical component and sensory quality were discussed through cluster analysis.Results (1) The clustering results showed that Hongda tobacco had strong regional characteristics on chemical component and sensory quality. For tobacco growing areas with similar distance, the chemical component and sensory quality of Hongda tobacco had high similarity. (2) The chemical component of Hongda tobacco in different regions had significant differences and the degree of variation was higher. The chemical component content of Hongda tobacco in Dali was higher and the chemical component content of Hongda tobacco in Qujing was lower. (3)The sensory quality score of Hongda tobacco in Dali was higher and the sensory quality score of Hongda tobacco in Qujing was lower.Conclusion The research has laid basis for planting plan, adjustment of cultivation techniques and choice of raw materials of Hongda tobacco.
