Abstract: Sensory quality of 37 samples of flue-cured tobacco leaves were evaluated and compared from Henan main tobacco-growing areas， and cluster analyzed on the basis of sensory quality. The results indicated that: The scores of sensory quality of flue-cured tobacco leaves ranged from 53.68 to 77.49， and indexes of sensory quality existed in certain variation. The scores of sensory quality of flue-cured tobacco leaves showed the trend of Jiaxian>Xiangcheng>Lushi>Lingbao>Linying>Fangcheng>Neixiang>Ruyang>Jiyuan for different tobacco-growing areas. Aroma quality， aroma quantity， concentration， physiological strength， offensive odor， irritancy， aftertaste and total scores of flue-cured tobacco leaves showed the trend of cutters>upper leaves>lower leaves for different stalk positions， and the scores of combustibility showed the trend of cutters>lower leaves>upper leaves. Sensory quality of flue-cured tobacco leaves had significant or highly significant difference among different stalk positions. As for the different colors， the averages of sensory indexes and total scores of orange-yellow leaves were higher than lemon-yellow leaves. Flue-cured tobacco leaves from Henan main tobacco-growing areas were divided into three categories by cluster analysis on the basis of sensory quality. The first category of flue-cured tobacco was from Lushi， Xiangcheng， Lingbao， Linying and Jiaxian， the second category was from Neixiang and Fangcheng， and the third category was from Jiyuan and Ruyang.
