Abstract
A reliable and effective tissue culture system was established for Perilla frutescens (perilla) using different cultivar, explant source, and growth regulator composition in medium. MS medium supplemented with 2.0 mg/L BA and 0.1 mg/L NAA was maximum at shoot induction. Cotyledon explants formed more shoots than hypocotyl explants. The frequency of plant regeneration through organogenesis was higher (22.8%) than that (6.1%) of somatic embryogenesis. Five genotypes of perilla were screened for the feasibility of shoot regeneration, cotyledon explant of ‘Manbaek’ showed the highest shoot induction at a frequency of 27.3% among the tested cultivars.
