Hybrid mushroom strain j9277 and its descendants

Abstract

A novel hybrid fungus culture, designated J9277, of the mushroom species Agaricus bisporus produces crops of mushrooms having white, rounded, thick-fleshed caps and proportionally long stems in a relatively short interval of time. Diverse additional strains can be developed from J9277 by various means including somatic and tissue culture selection, basidiospore selection, and hybridization to other strains of Agaricus bisporus , and the resulting derivative strains can be screened for desirable commercial characteristics.

1 . A method for producing a mushroom culture of  Agaricus bisporus  produced by a one method selected from the group consisting of the propagation and selection of somatic subcultures of the culture of  Agaricus bisporus  designated strain J9277, a representative culture of said hybrid strain J9277 having been deposited under ATCC Accession No. PTA-6692, or at least one strain developed therefrom, the regeneration and selection of cultures from tissue explants of mushrooms of the culture of  Agaricus bisporus  designated strain J9277, a representative culture of said hybrid strain J9277 having been deposited under ATCC Accession No. PTA-6692, or at least one strain developed therefrom, and the selection of basidiospores of mushrooms of the culture of  Agaricus bisporus  designated strain J9277, a representative culture of said hybrid strain J9277 having been deposited under ATCC Accession No. PTA-6692, or at least one strain developed therefrom. 
     
     
         2 . A mushroom culture of  Agaricus bisporus  produced by hybridization of a first strain and a second strain of  Agaricus bisporus , wherein at least one of said first and second strains of  Agaricus  is the culture of  Agaricus bisporus  designated strain J9277, a representative culture of said hybrid strain J9277 having been deposited under ATCC Accession No. PTA-6692, or at least one strain developed therefrom. 
     
     
         3 . A mushroom culture of  Agaricus bisporus  produced by the introduction of novel genetic material by any means, including DNA-mediated transformation, into the culture of  Agaricus bisporus  designated strain J9277, a representative culture of said hybrid strain J9277 having been deposited under ATCC Accession No. PTA-6692, or at least one strain developed therefrom.
