摘要:
A method for the production of high proportions of homokaryons among spores from breeding stock of the mushroom Agaricus bisporus includes the steps of providing a first strain of Agaricus bisporus carrying a gene or genes which determines the trait for production of basidia which predominantly bear at least three spores rather than two, and crossing the first strain of Agaricus bisporus with a second, different strain of Agaricus bisporus.
摘要:
Methods of producing hybrid Agaricus bisporus mushrooms strains derived or descended from at least one wild mushroom strain and having the specified traits of either greatly diminished sporulation or an absence of sporulation, and of obtaining postmeiotic offspring of nonsporlating basidiomycete fungi including Agaricus bisporus, are disclosed.
摘要:
A method for the production of high proportions of homokaryons among spores from breeding stock of the mushroom Agaricus bisporus includes the steps of providing a first strain of Agaricus bisporus having tetrasporic ancestry and which carries a gene or genes that determines the trait for production of basidia which predominantly bear at least three spores rather than two, and crossing the first strain of Agaricus bisporus with a second, different strain of Agaricus bisporus to form at least one hybrid heterokaryotic culture. The culture is capable of producing mushrooms having basidia which predominately bear at least three spores, many of which are homokaryotic. The homokaryons taken from the homokaryotic spores can be used in crosses to produce new hybrid strains of Agaricus bisporus mushrooms which may exhibit improvements with respect to various traits including productivity, rate of development, disease resistance, aesthetic qualities and the like. Also, the homokaryons can be used to map genes that control phenotypic traits of interest.

摘要:
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.
摘要:
The present invention provides improved mushroom cultivation materials which are amenable to improved uniformity of application to mushroom beds. The invention features such materials having particulate indicator therein having a color which is discernable from the organic substrates of the cultivation materials. The application may be followed under incandescent, fluorescent or ultraviolet light or in accordance with other means.
摘要:
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.

摘要:
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.
