Analysis on tobacco leaf quality of K326 in different ecological zones of neutral flavor type

To analyse the equality and characteristics of the main tobacco cultivar K326 in different ecological zones of neutral flavor type, field tests were set up in six tobacco main growing areas to analyze the appearance quality, chemical components and sensory quality of its flue-cured leaves. The results showed that, the tobacco appearance quality, chemical components and sensory quality were significantly different in different tobacco areas. The appearance quality of K326 in Zunyi, Wulong, Mengyin was better . The tobacco total sugar , reduction sugar and sugar/nicotine were more appropriate in Zunyi,Wulong and Xunyang. The Nicotine, total nitrogen, Cl- and K+/Cl- were appropriate in all these sites. The content of K was higher in Sangzhi and Zunyi (more than 2%) . The taste score and flavor quality of cutters were higher in Wulong, Zunyi and Sangzhi. In summary, as the high quality variety in six pilot sites, K326 is more appropriate in Zunyi and Wulong.
