NEW HYBRID AGARICUS BISPORUS MUSHROOM STRAINS

The invention relates to the field of microorganism strain development， more particularly to the development of heterokaryotic hybrids of the fungus species Agaricus bisporus. Even more particularly， the invention relates to white Agaricus bisporus hybrid strains having improved characteristics for the users (namely the growers， the processers and the consumers). These hybrids are for example the deposited strains CNCM I-4945 and I-4946， originating from a cross plan involving the deposited line CNCM I-4948. The invention relates to strains derived from these hybrids and also progenies derived from these hybrids.
