Phytochemistry of Daucus carota wild populations in Corsica (France)

The Daucus carota diversity in Corsica (France) was previously investigated both at the morphological and genetic levels (Reduron et al., 2017). As wild carrot is rich in essential oils and volatiles, phytochemical compounds might represent a valuable diversity descriptor. A phytochemical analysis was conducted across 25 populations belonging to different infraspecific taxa and originating from various sites of Corsica Island. The analyzed organs were ripe fruits, seedling roots and seedling leaves. Compounds were identified and quantified by gas chromatography/mass spectrometry. Biochemical results analyzed by Principal Component Analysis (PCA) bring into evidence 6 populations possessing a distinctive chemical profile
