Title: Producing New Strains of Agaricus bisporus
Author: K. Stubnya

Abstract:

Although intensive mushroom growing has a long and considerable past throughout the world we did not know much about the biology of propagation of the Agaricus bisporus until the last two decades.

“Breeding of the commonly cultivated mushroom Agaricus bisporus has become possible from our knowledge of its life cycle (Raper et al., 1972.) but the nature of the life cycle is such as to make a breeding program tedious and difficult.” (Raper and Raper, 1972). “The characteristic self-fertility of single-spore isolates due to a type of sexuality known as secondary homothallism renders the genetic manipulation to improve strains far more cumbersome than would be the case if the species were heterothallic with self-sterile cross-fertile progeny.” (Raper, 1974).

Pritsche reported theoretically based experiments in 1964. This report dealt with the continuous reproduction of monospore cultures, its properties and combination possibilities.

Elliott, Miller, Kananen and Raper and Raper reported that the cultivated mushroom Agaricus bisporus can be cross fertilized. (1972. Mush. Sei. VIII. London).Considering these reports we began our work in 1973 at the Research Laboratory of “DUNA” Agricultural Co-operative, Budapest Hungary.

The aim of our work which I shall discuss in the following is the production of strains of Agaricus bisporus with better properties than the strains grown hitherto.
