Title: Strain Evaluation on Agaricus bisporus
Authors: B.L. Dhar and J.N. Kapoor


The development and selection of new and improved strains of the commercial mushroom, Agaricus bisporus (Langer) Sing, is a continuous process and the easiest approach to better production. Strain improvement results in better sporocarp quality for various market outlets, less shrinkage in processing and resistance to diseases and insect pests, better keeping quality etc. Selection of superior strains through evaluation would appear to be one of the best ways of improving crop yields without increasing costs of production.

Some work has been done in strain improvement and evaluation as has been reported by Lambert (1959), Kneebone (1959, 1968), Kneebone et. al.(1972) and Kaul and Kachroo (1975). Cultures from single spores, multispores, tissue, mycelial transfers and use of mutagenic agents have all resulted in the isolation of improved strains which have vastly increased the spectrum of germ plasm available to spawn makers. Selection of a strain suitable for a particular set of conditions is important and pre-requisite for starting commercial mushroom cultivation. All the strains used in the present study are of exotic origin and these strains have been used by different workers in India for mushroon growing without evaluation. It was with this aspect in view that the present study was undertaken.
