title: [A study on the breeding of new Ganoderma varieties by UV induced mutagenesis].
abstract: UV induced mutagenesis of Ganoderma's protoplast was carried out. By crude screen and careful screen, we obtained two mutants, 43020# and 43026$, whose dry weight and polysaccharides contents are higher than original strain. Results of continued cultivation for 10 generation on PDA slants and successive tests of shaking bottles, and successive 3 time pilot scale tests at 3 tons, showed that these two mutants are excellent strains with steady properties, high production and high content of polysaccharides. This study has provided a rapid and effective method for breeding of Ganoderma varieties which is suitable to industrial fermentation.
