Abstract: Application of factor analysis and cluster analysis on blending and threshing techniques for tobacco was performed by using conventional chemical composition  as indicator.Factor analysis showed that three factors affecting the tobacco quality signifcantly were nitrogen,nicotine and total sugar/nicotine ratio.It can be concluded by cluster analysis that there are mainly five different types of tobacco,i.e. Xiangxi Longshan C3F,C2F,B1F,C1F tobacco and Sichuan Pangzhihua B3F tobacco;Xiangxi Longshan CX2K,X34 and X3F toabcco;Xiangxi Longshan B4F,C4,X4F toabcco and Sichuan Pangzhihua B2F,C3F and B2L tobacco;Xiangxi Longshan CX1K,B1K,C1L tobacco;Xiangxi Longshan B2K,X2F,B23 and B2L tobacco.Similar quality for each type of tobacco indicated that these tobaccos can be blended for the following threshing procedure.

Key words: tobacco, blending and threshing techniques, factor analysis, cluster analysis
