Abstract:		"Scent is one of the most important economic traits in Freesia hybrida. 'Shiny Gold', a popular cultivar in South Korea, is widely cultivated for its scent. The relative scent intensity of 'Shiny Gold' was approximately 16% higher in full-bloomed flower when compared to the yellow bud stage, while tissue-specifically, tepals showed higher intensity in electronic-nose (e-nose) analysis. E-nose analysis also showed that the scent intensity of 'Shiny Gold' was higher and lower than '10C3-424' and '10C3-894', respectively, and was similar to 'Yvonne'. These results correlated to those of the olfactory tests. In total, 19 volatile compounds, including linalool, beta-ocimene, D-limonene, trans-beta-ionone were detected in gas chromatography-mass spectrometry analysis. Among these, linalool was the major volatile compound, accounting for 38.7% in 'Shiny Gold'. Linalool synthase and TPS gene expression corresponded to the scent intensity of the four cultivars, with the lowest expression in the '10C3-424'. TPS 2, TPS 3, TPS 5, TPS 6 and TPS 8 were highly expressed in both bud and flower in 'Shiny Gold', while the expression of TPS 4 was lower, relative to other TPS genes in both the flowering stages. These results may aid in enhancing scent composition in Freesia cultivars using marker-assisted selection"
