Floral scent compounds of 13 wild lines of
Camellia lutchuensis T. Ito ex Matsum. collected from Okinawa,
C. lutchuensis line 1118, which is one of the pollen parents of fragrant camellia cultivar, and 4 fragrant camellia cultivars were compared. Limonene and 6 aromatic compounds,
o-anisic acid methyl ester, benzaldehyde, benzyl benzoate, eugenol, methyl salicylate and phenylacetaldehyde were newly identified as scent compounds of
C. lutchuensis. The total amounts of scent compounds in most of 13 wild lines, especially lines 3 and 36, were more than those of line 1118. Floral scent of line 36 with a high composition ratio of 2-phenylethanol and phenylacetaldehyde with floral note was considered stronger than that of line 3. Floral scent compositions of fragrant camellia cultivars, ‘Himenoka’, ‘Minato-no-akebono’, ‘Shunpu’ and ‘Fragrant pink’ were also almost the same as that of
C. lutchuensis. However, those composition ratios differed greatly in each cultivar, and the floral scent of ‘Himenoka’ and ‘Minato-no-akebono’ with a high composition ratio of floral note compounds was considered stronger than those of the other 2 cultivars.
