Essential oils from new pigmented Citrus hybrids: Citrus sinensis L. Osbeck x C. clementina Hort ex Tanaka

The chemical composition of the essential oils of 2 new pigmented Citrus hybrids (Omo-6 and Omo-12)was studied by gas chromatography-mass spectrometry (GC-MS). The hybrids were obtained by crossbreeding the orange Citrus sinensis (L.) Osbeck cultivar 'Moro' and clementine Citrus clementina Hort ex Tanaka cultivar 'Oroval'. Seventy-eight components were fully characterized and grouped in five classes (monoterpene hydrocarbons, oxugenated monoterpenes, sesquiterpenes, aliphatic alcohols and esters, and aliphatic aldehydes) for an easier comparison of the oils with parents and those of 2 previously analysed hybrids (Omo-15 and Omo-31) from the same crossbreeding procedure.
