Backcrossing means taking an offspring and crossing it back to one of its parents, and it is the standard way to pull a single trait like purple colour or a specific smell into a stable line. It only works with regular seeds because you need a male from the cross to pair with the original mother. A worked example over three generations is shown at https://breederregularseeds.com, which made the concept far less abstract for me. The downside is that each round also concentrates whatever faults that parent had.
