Screening of Flue-cured Tobacco Varieties Based on Climate Conditions and Quality of Tobacco Leaf

A screening experiment of flue-cured tobacco varieties was conducted in raw materials base unit of Jiangsu Tobacco Industry, with Yunyan 87, K326, Qianxi1, binna1, Nanjiang 3, Jiucaiping 2 and Dujuan1 as experimental materials. Based on the comparative analysis of similar climatic conditions between Dafang of Bijie and other high-quality tobacco-growing areas, the chemical indexes of flue-cured tobacco usability and sensory quality of different varieties were studied to evaluate the quality of tobacco, with the purpose of providing theoretical support for the selection of tobacco varieties. The results were as follows: The climatic conditions of Dafang was similar to that in Sanming, Zimbabwe and Brazil, with cosine value above 0.95, especially in Sanming (with cosine value up to 0.98). The leaf chemical availability index (92.14%) and the sensory quality of Yunyan 87 was the highest among the tested varieties. In summary, Yunyan 87 was the most suitable variety in Jiangsu Tobacco Industry Dafang base unit.
