Exploration of Screening and Evaluation Methods for Characteristic Flue-cured Tobacco Varieties in Shaoguan Based on Chemical Component Usability
In order to clarify the availability of chemical components of tobacco leaves in Shaoguan and explore the best evaluation method for the availability of chemical components in tobacco leaves,the local planted variety Yueyan 97 was used as the control,and the chemical components availability index and local penalty variable weight model were used to evaluate the chemical components characteristics and availability of three characteristic flue-cured tobacco varieties,including Honghuadajinyuan(HD),Cuibi NO.1(CB-1)and Zhongyantexiang 301(Zhongyan 301)at 3 experimental points.The results showed that the chemical composition of the three special flue-cured tobacco varieties varied greatly at different test sites in Shaoguan.The CCUI value of Zhongyan 301 was closed to the control variety Yueyan 97,while CB-1 was in the middle,and HD was lowest.The F(variable weight)value of Zhongyan 301 was slightly lower than that of Yueyan 97,but higher than that of HD and CB-1.In general,the chemical composition availability of Zhongyan 301 is relatively high in Shaoguan,which can be further studied.
