method for preparation of monokaryons of basidiomycetes and dikaryons out and edible mushrooms.

摘要

The invention relates to a process for producing monokaryons of dikaryotic strains of Basidiomycetes by chemical means, for instance Pleurotus ostreatus, Kuehneromyces mutabilis, Flammulina velutipes or Lentinus edodes under gentle conditions so that essentially two monokaryons result per dikaryon-containing hyphal compartment. These monokaryons can be used for mating with compatible partners to give dikaryotic Basidiomycetes strains.
