Abstract: A hybrid mushroom culture of Agaricus bisporus, designated as strain B14528, includes a representative culture of the strain, which has been deposited under NRRL Accession No. 50900. A method of producing a hybrid mushroom culture of Agaricus bisporus comprising: mating a homokaryotic line J12998-s39 with a homokaryotic line BW-s191. Additionally, mushrooms, parts of the culture and products incorporating the culture are provided.

Abstract: 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 a hybrid mushroom culture of Agaricus bisporus designated strain J9277. 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. One resultant class of the mushroom Agaricus bisporus (J. Lange) Imbach is the hybrid strain J10165. It exhibits an attractive appearance that includes a smooth, bright white cap, and is biologically incompatible with strains of the ‘U1’ lineage group. A method for improving facility hygiene and reducing disease incidence at any commercial Agaricus bisporus mushroom production facility is also provided.

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.

Abstract: A new and unique variety of the mushroom Agaricus subrufescens Peck was produced by crossbreeding a single spore isolate from the fungal strain ‘I-101’ and a single-spore isolate from the fungal strain ‘SBRFG’. The resultant hybrid, named ‘H1X1’, exhibits early cropping, large size, high productivity, and an attractive appearance that includes a smooth, round cap.
