In order to explore the current situation of tobacco leaf quality in Kunming,and to screen the flue-cured tobacco varieties that meet the needs of the"Huangshan"cigarette brand,8 towns and villages in 4 different ecological sub-regions of Kunming were distributed for the comparative experiment in the same fields with the imported two new flue-cured tobacco varieties of Yunyan 121 and YN223,compared with the local main cultivars,including Hongda,MSK326 or MSYunyan 87,to test and evaluate the processed middle tobacco leaves according to the Huangshan Brand's demand for raw materials quality.The results showed that:1)the appearance and sensory quality of tobacco leaves were mainly affected by ecological subregion,while the tobacco varieties only affected the smoke style.2)The appearance quality,chemical index and sensory quality of tobacco leaves in Kunming were good in general,but there were some deficiencies such as high-content sugar with low-content nicotine,high-content nitrogen with low-content nicotine and low-content potassium,and the content of oil content,color,aroma and sweetness of tobacco leaves need to be improved.3)Yunyan 121 can be used as a back-up flue-cured tobacco variety of Huangshan cigarette brand in Kunming production area and further field trials and demonstrations as well as industrial usability verification.To sum up,the study screened out the reserve varieties in line with the"Huangshan"brand,and explored the current status of tobacco quality in Kunming and the direction of quality improvement.
