title: [The breeding of Phellinus baumii by protoplast fusion].
abstract: OBJECTIVE
  To breed good strains by protoplast fusion in Phellinus baumii.
  
  
  METHODS
  5.8S rDNA-ITS sequences, mycelial growth rate, mycelial biomass and exopolysaccharides (EPS) production of 7 strains in different origins were analyzed, respectively. Then the inactivated parent protoplast and the PEG induction were used in the process of protoplast fusion.
  
  
  RESULTS
  The strain P. baumii SA02 and P. baumii SA04 were selected as the parent strains. R002, R003 and R005 had antagonistic effects with parent strains.
  
  
  CONCLUSIONS
  R002, R003 and R005 are fusants of the parent strains.
