Perilla cultivar ‘Deulsaem’ was developed for perilla oil and powder. ‘YPL139’ and ‘Daesildeulkkae’ crossed in 2003 and selected from F₃ to F₅ by pedigree method. The selected pedigree is ‘YPS142-B-28-1-3-2-2’ and named as Miryang No. 57. The regional yield trial (RYT) in five regions was conducted from 2011 to 2013. In RYT, ‘Deulsaem’ was a high yield and quality. ‘Deulsaem’ is determinate, white flower and brown spherical seed. Maturity date was Oct. 8, similar to ‘Saeyeopsildeulkkae’(standard cultivar). However, ‘Deulsaem’ has higher number of flower cluster and ear per cluster than ‘Saeyeopsildeulkkae’. The yield of oil content and linolenic acid of ‘Deulsaem’ was 39.4% and 61.0%, respectively. The yield in adaptable regions was 1.42 ton/ha (5% increase compared to ‘Saeyeopsildeulkkae’) and ‘Deulsaem’ is expected to be cultivated and used widely for good quality perilla oil.
