The chemistry, aroma, solubilities (hexane and 95% ethanol), and smoking quality of cured tobacco from three typical flue-cured varieties that produce glandular trichomes on the surface of the green leaf and an atypical aglandular breeding line were compared. The glandular tobaccos produced more characteristic tobacco aroma than the aglandular tobacco. More hexane-extractable solute was obtained from the aglandular tobacco than from the glandular flue-cured tobaccos, but more alcohol-extractable solute was obtained from the glandular types. A trained smoke panel gave higher scores to the aglandular tobacco than the three glandular varieties. Larger quantities of total volatiles were obtained from the aglandular tobacco. Solanone and oxysolanone identified from the glandular tobacco were absent in the aglandular breeding line. The aglandular tobacco was higher in total alkaloids and lower in reducing sugars than the glandular types
