GLC analyses of essential oil fractions from 215 local varieties of Perilla frutescens showed that they can be classified into 5 types based on the main component of the essential oil fractions, i.e. Perillaldehyde type (PA), Elsholtziaketone type (EK), Perillaketone type (PK), Citral type (C), and Phenylpropanoid type (PP). These chemical phenotypes were found to be inherited from parent to progeny through self-pollination without accompanying genetic segregation. The essential oil composition of F_1 hybrid, PK x EK, was found to be very similar to that of EK type, which suggests that EK type is phenotypically dominating PK type. However, both F_1 hybrids derived from the crosses, PP × EK and PP x PK, produced a novel essential oil phenotype (L-PA) containing l-limonene as a main component and perillaldehyde as a minor component. Such accumulation of l-limonene in those F_1 hybrids may be due to the genetical suppression of conversion of l-limonene, possibly a biosynthetic intermediate, into perillaldehyde.
