‘Soim’ is a new leaf vegetable perilla (Perilla frutescens var. japonica Hara) variety developed from the cross between Ipdeulkkae1 and YCPL173 at the Department of functional crop, NICS, RDA, in 2009. Uniform perilla leaf size is one of the most important characteristics for reduction of manpower. To harvest uniform perilla leaf, farmers cultivate just main stem and remove all branches. The next harvest leaves grow well, so farmers gain high leaf yielding and efficiency of harvest leaf. ‘Soim’ grows vigorously and yields high quality leaf with larger size of the next harvesting leaves compared with a check cultivar, ‘Ipdeulkkae1’. For the leaf production, ‘Soim’ is adaptable to whole arable land in South Korea. However, because of its late maturity, seed production cultures need rain shield. No. of breeder’s right: 4387.
