Intercultivar Diversity of Sour Orange (Citrus aurantium L.) Based on Genetic Markers, Phenotypic Characteristics, Aromatic Compounds and Sensorial Analysis

Sour oranges (Citrus aurantium L.) are well known in the processing and cosmetics industries for aromatic properties of their essential oils. Intercultivar genetic diversity is not documented. The objective this study was to evaluate impact morphological selection mechanisms varietal diversification (mutation or hybridization) on odor variability sour orange Forty-five accessions from INRAE-CIRAD citrus Biological Resources Center (France) were assessed ten simple sequence repeat (SSR) 54 single nucleotide polymorphism (SNP) markers, nine morphochemical fruit traits with components leaf peel Thirty-nine displayed no intercultivar molecular six genotypes originated interspecific hybridizations involving orange, citron, pummelo mandarin. oil (PEO) low, accordance diversity. predominance limonene (>90%) prevents any possible correlation be made between composition variation sensory profiles detected by panelists. Few compounds (LEO), such as linalool, linalyl acetate, ?-terpineol geraniol significantly different across varieties. attributes mainly used differed highly main genetically identical group accessions. These results confirm that mutation can generate aromas exploitation requires an improvement characterization processes.
