Culture Trials
When a number of strains have been generated from a sporeprint, they are different because of
recombination in the basidium. Some of the strains MAY be identical to the parent strain, but that
must demonstrated by some testing procedure. As in any screening operation, the more strains
used, the better the chance of a good result. In fact, professional mushroom breeders often do trials
with thousands of strains at a time. This kind of work, however, takes large and expensive facilities,
and is unnecessary if the purpose is simply to find a strain which fruits well under a certain set of
conditions. A strain which fruits well in test batches under uniform conditions has a high likelihood
of doing well in larges batches when the same conditions of temperature, humidity and aeration are
maintained. How many strains need to be tested? If the mushroom being worked with is tetrapolar,
only one third of the dikaryotic colonies picked out will be capable of fruiting at all. In order to make
trials often fruiting strains, begin with at least thirty dikaryotic strains.

Many mushrooms, especially the wood-rotters, fruit on enriched agar media in a petri plate if
given proper temperatures and some light. If the mushroom being tested is one of these, the selection of fruiting strains is simple. A mushroom requiring a special substrate or additive to fruit should
be provided with the smallest amount allowable. For example, Agaricus brunnescens can be fruited
on 50 grams of sterilized grain in a pint jar, if it is cased with soil containing certain bacteria. The
