To develop novel strains of sporeless mutants, protoplasts derived from a commercial strain of Pleurotus sp. were irradiated with 320 MeV of carbon ion beam. As a result, three sporeless mutants were obtained with the dose of 40 Gy, 80 Gy and 160 Gy. In addition, nine other mutants with different traits such as pileus color from the original strains were obtained. Morphological and cultivation characteristics of these mutants suggested that 20 Gy or 40 Gy were thought to be adequate for developing sporeless mutants with sufficient quality for commercial use.
