Abstract: In order to facilitate the evaluation of quality traits of cigar germplasm resources, this paper conducted simple correlation and typical correlation analysis on the chemical components, polyphenol and sensory quality of 50 cigar germplasm resources by DPS (data processing system). The results showed that there were significant typical correlations between the chemical components and polyphenol, sensory quality of cigar germplasm resources. The relation between the chemical component and sensory quality was the closest, that with polyphenol was closer, and that between polyphenol and sensory quality was close. The results also revealed that the reducing sugar, total nitrogen content, potassium, nicotine had close correlation with the polyphenol (cryptochlorogenic acid, neochlorogenic acid, chrysatropic acid, chlorogenic acid); and chemical components (reducing sugar, total sugar,etc.) also had close correlation with sensory quality (concentration, aftertaste, irritation, aroma quality, gray, offensive odor) ; while the polyphenol (neochlorogenic acid, cryptochlorogenin acid, chrysatropic acid) had closer correlation with sensory quality (aroma quality, aroma quantity, irritation). These results showed that there were certain correlations between chemical components, polyphenol and sensory quality of cigar germplasm resources.
