Inheritance and Flavor Contribution of 2-Isobutylthiazole, Methyl Salicylate and Eugenol in Tomatoes1

open access: yesJournal of the American Society for Horticultural Science, 1970
Abstract The volatile compounds of tomato cultivars ‘Campbell 146’ and ‘Campbell 1327’ were studied by gas-liquid chromatography. Heritable concentration differences were found for 3 compounds identified by retention time and infrared spectroscopy as 2-isobutylthiazole, methyl salicylate and eugenol.
