Abstract
Fungicide resistant mutants of Agaricus bisporus, the cultivated mushroom, have potential as markers for use in the production of novel hybrid mushroom strains and offer prospects for use in disease control programmes. Uv mutagenesis was used in an attempt to induce resistance to four fungicides (benodanil, carboxin, imazalil and tridemorph) in different strains of A. bisporus. Despite the frequent isolation of strains with transient resistance, stable phenotypic resistance was induced in single strains to both benodanil and tridemorph and in two different strains to carboxin. Imazalil resistance was not obtained despite numerous treatments in different strains. All mutants showed enhanced in vitro tolerance to specific fungicides when compared with the parental strain. Cross resistance was found to occur between mutants with specific resistance to either benodanil or carboxin. Fruiting ability was assessed in compost culture. The tridemorph mutants were altered in colony morphology and were not fertile. All other mutants produced were fertile and retained the agronomic characteristics of the strains from which they were derived.
