Your hypothetical apple-grower family would simply share a handbook which meticulously shared the initial species of apple used, the breeding protocol, the hybridization method, and any other factors used to breed this perfect apple. Having the handbook and materials available would make it possible for others to reproduce the resulting apple, or to obtain similar apples with different properties by modifying the protocols. The handbook is the source code. On the other hand, what we have here is Monsanto saying: "we've got those Terminator-lineage apples, and we're open-sourcing them by giving you the actual apples as an end product for free. Feel free to breed them into new varieties at will as long as you're not a Big Farm company." Not open source.
