A STUDY ON THE BREEDING OF NEW GANODERMA VARIETIES BY UV INDUCED MUTAGENESIS
原生质体紫外诱变选育灵芝新菌种的研究

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.
