Abstract A large number of viable protoplasts were produced by enzymatic digestion of Gracilaria asiatica vegetative tissue. The protoplasts underwent initial division after 5–7 d in culture and developed into callus-like cell-masses. Many filaments grew from the periphery of these cell-masses and disappeared after about one month in culture. Simultaneously, the central part of the callus-like cell-masses thickened and its color deepened. The first buds appeared from the center of the cell-masses and developed into whole plants after three months in aerated culture. Many new buds formed around the first plant and more than 20 plants grew per callus-like cell-masses in less than four months. Filaments taken from callus-like cell-masses developed into young plants after about 20 d of culture.
