Abstract: Correlation, regression, and path analysis between agronomic attributes in cigar wrapper tobacco and its roots bleeding intensity during field growth were conducted. The correlation analysis showed that plant height, stem length, length of joins of main stem, leaf area, leaf weight, root volume, and root weight were related to the root bleeding intensity positively and correlation coefficients were significantly different, which were 0.8449**、0.8552**、0.8379**、0.8215**、0.8204**、0.8442**、0.7156** respectively. Dry weight of stem was related to the roots bleeding intensity positively and correlation coefficient of dry weight of stem with the roots bleeding intensity was different(r=0.6926*). The result of path analysis and regression indicated that plant height, area of leaf, volume of root, and dry weight of root were key factors for the roots bleeding intensity.
