How does this work? And I'm talking like accessible to home gardeners and not professional labs or something which use molecular and genetic engineering.
So how does this go?

1: Do you breed with parent plants that are perhaps not resistant themselves, but not infected either and hope the following generation(s) are by testing them for that disease. If some of the progeny are, you select those specimens to continue breeding and improve the line.

2. If none of the progeny are, do you keep trying with the same parents, or ditch them as possible parents and look for new parent plants?

3. Can you also use parent plants that are infected with the disease to breed a resistant line (and bet on dumb luck) or ditch those too and only breed with non-infected plants?
