Substrain Development

As generations of mushrooms progress from one parent to the next via spore collection, what is happening when people select more vigorous strains? I understand that there may be a slight effect on potentcy also. I guess im just trying to figure out how to sellect the best mushrooms/mycelium to use for the next batch. I would think that all of the spores from a fulsh would contain the same genetics, but since there is evidence of a change over generations, they must not be 100% identical, how is one to know what to look for and select for future propagation?

You don't.
Spores in this regard are like sperm and eggs. Look at a family with ten kids. All ten are different. Some are taller, some are smarter, some are meaner, etc. Each time you go back to spores, you have to select a substrain that has the qualities you want. RR

so is the only true way to preserve the strain, once you found one you like, through direct mycelium inoculation?

Correct. If you'll keep your master cultures in the refrigerator in test tubes, you can remove a very small piece once every few months to keep fresh material for growing. Once a year, remove a small piece from the test tube, and let it grow in a petri dish for three days or so, then remove a small piece from the petri dish and use it to inoculate a fresh test tube. If you'll do this, you can keep the same culture for twenty years or more without any problems from senesence. RR
