Chrysanthemum is one of the three major floricultural crops in the world, accounting for 10 percent of domestic floriculture production. Floral scent is an important trait in the breeding of flowering plants, and hence a study on the scent of diverse chrysanthemum cultivars can provide useful background for the future advances of breeding new cultivars. The floral scents of twenty different chrysanthemum cultivars were comparatively analyzed by electronic nose equipped with 6 metal oxide sensors. Ray florets and disc florets were separately investigated to compare the scents patterns between two floret types of each cultivar. In the principal component analysis (PCA) and discriminant function analysis (DFA), the scent patterns of most cultivars were located close to each other, but the scent patterns of ‘Green Diamond’, ‘Peach Pangpang’, and ‘Manito’ were distributed in distinct positions compared to other cultivars. As a result of measuring the distance from the control (air) to the sample, the distance of ‘Manito’ was the highest among 20 cultivars, and ‘Peach Pangpang’, ‘Baekgang’, ‘Angel’, and ‘Coral Beach’ showed a higher distance. These results suggest that ‘Manito’, ‘Peach Pangpang’, ‘Baekgang’, ‘Angel’, and ‘Coral Beach’ have higher scent intensity than other cultivars. Radar plots obtained from the six sensor arrays showed different scent patterns for each cultivar. Especially, most cultivars showed a relatively higher response in the PA/2 sensor compared to the other sensors. Radar plots comparing the floral scent characteristics of two floret types of 20 chrysanthemum cultivars showed that the disk floret had stronger scent intensity than ray floret in 18 cultivars except for ‘Geumbitnuli’ and ‘Peach Pangpang’, which have the smaller disk florets than those of other cultivars.
