Abstract: A method for excluding an aggressive incompatibility (AI) trait from Agaricus bisporus mushroom strains, wherein the method includes mating a culture of a hybrid mushroom line designated B18287-s82, a representative culture of the line having been deposited under NRRL Accession No. 68168, with a culture of the white mushroom line designated WBL-s290, to obtain an F1 hybrid mushroom strain designated J19109, a representative culture of the F1 strain having been deposited under NRRL Accession No. 68163. Upon fruiting a culture of the new F1 strain designated J19109 to obtain homokaryotic spores therefrom, one obtains cultures of homokaryotic lines from the homokaryotic spores from F1 strain J19109 and selects a culture of a homokaryotic line from the F1 strain J19109. The culture of a homokaryotic line from F1 strain J19109 is mated with a culture of the mushroom line designated J11500-s80, to obtain an F2 hybrid mushroom strain.

Abstract: A mushroom culture of Agaricus bisporus, comprising at least one set of chromosomes as a culture of line J14756-s3, includes a representative culture of the line, which has been deposited under NRRL Accession No. 67317. A method of producing a hybrid mushroom culture of Agaricus bisporus comprising: mating a culture comprising at least one set of chromosomes as a culture of line J14756-s3 with a second homokaryotic line culture. Additionally, mushrooms, parts of the culture and products incorporating the culture of the invention are provided.

Abstract: The present invention relates to the development of a homokaryotic Agaricus bisporus (Lange) Imbach mushroom fungus line culture designated N-s34 and to cultures obtained, descended, or otherwise derived from line N-s34. More particularly, the present invention relates to cultures incorporating at least one set of chromosomes having a genotype present in the genotype of the chromosomes found in line N-s34. The present invention further relates to F1 hybrids, and to a particular F1 hybrid strain, designated LA3782, descended from N-s34. This particular strain indeed displays an excellent yield weight of the harvested crop, especially in the third-flush, and a very good shelf-life of the mushroom products. The invention additionally relates to progeny, lines and strains derived from or descended from, or otherwise developed or obtained from, line N-s34 and from said hybrid strain LA3782. The invention further relates to methods of use of the cultures described hereinabove.

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.

Abstract: A method of controlling toxic fungal diseases in mushrooms is provided which comprises adding an effective fungal-disease-inhibiting amount of a compound of the formula ##STR1## to a substrate in which mushrooms are growing or are to be grown, wherein R represents --CH.sub.2 OH or --CHO; n is an integer from 0 to 3; and each R.sup.1 independently represents halogen, OH, NH.sub.2, or an organic substituent containing from 1 to 10 carbon atoms and from 0 to 5 heteroatoms, wherein the total number of carbon and heteroatoms in all R.sup.1 substituents is no more than 15.
