Volatiles from flowers of several lucerne (Medicago sativa complex) genotypes, belonging to different taxonomic groups and characterised by various flower colours, were isolated by Tenax-trapping and analysed by GC and GC-mass spectrometry. Thirty-three compounds were identified, including aldehydes, alcohols, esters, ketones, terpenes and furanoids. Trans-2-hexenal was the most abundant volatile in all genotypes. Ranking of individual volatile compounds was similar in all genotypes but absolute values (μg g⁻¹) for each compound varied widely from genotype to genotype, being largely associated with flower colour intensity. In terms of total volatile quantity, the following ranking of flower colours was observed: dark green > violet > bright or light yellow.
