Fragrance is one of the major characteristics of floricultural crops, and the organization of fragrance information into a database is essential for enhancing breeding efficiency of these crops. Specifically, given the limited fragrance information available for Korean domestic chrysanthemum cultivars, conducting fragrance analysis on these cultivars is necessary to establish and effectively utilize a core germplasm of chrysanthemums. The fragrances of 22 different chrysanthemum cultivars were comparatively analyzed using an electronic nose equipped with 6 metal oxide sensors. Ray florets and disk florets of each cultivar were separately investigated to compare the fragrances between the two floret types. The principal component analysis (PCA) and discriminant function analysis (DFA) showed that the fragrances of all cultivars could be distinguished from the control group (air). Particularly, the scent patterns of ray florets in ‘Fresh Carpet’ and disk florets in ‘Cherry Pink’ were notably distinct from the fragrances of the other cultivars. Radar plots obtained from the 6 sensor arrays exhibited distinct scent patterns for each cultivar. Among these plots, ray florets of 4 cultivars including ‘Orange Marble’ and ‘Fresh Carpet’ had stronger fragrance intensity compared to their disk florets. Conversely, for other 13 cultivars such as ‘Vivid Scarlet’ and ‘Black Marble’, fragrance intensity was higher in the disk florets than in the ray florets. The other 5 cultivars such as ‘Early Bird’ showed similar fragrance intensity between the ray florets and disk florets. To compare relative fragrance intensities among each cultivar, the Euclidean distances between the control and the samples were examined. The results revealed that the disk florets of ‘Cherry Pink’ had the strongest fragrance, and ‘Orange Pangpang,’ ‘Yellow Marble,’ and ‘Pink Diamond’ exhibited strong fragrances.
