“Ilyeop” (Perilla frutescens (L.) Britton), a new cultivar for leaf vegetable, was developed from a cross between Ipdeulkkae1 and YCPL187 at the National Yeongnam Agricultural Experiment Station, RDA, in 2001. For the cultivation of leaf vegetable perilla, the plants are grown with a spacing of 10 × 5 cm between rows and plants and all branches are removed to harvest uniform leaves from main stem, indicating that the amount of the next harvesting leaf is a important characteristic for the growth of the plant. “Ilyeop” grows vigorously and yields high quality leaf with higher amount of the next harvesting leaves composed with a check cultivar, “Ipdeulkkae1”. “Ilyeop” has five days of earlier seed maturity (Oct. 24) than that of “Ipdeulkkae1” under natural condition, less chance of frost damage is expected. The flowering date of “Ilyeop” is same with that of “Ipdeulkkae1” in winter cultivation with night break treatment.
