just grow 1 plant and clone it by taking clippings......
or you can grow a bunch. Replant the 2nd generation and keep the ones most like the traits you like, then keep replanting each year until you have "de-hybridized" them but keeping the plants with the traits you like...
The easy way is just clone a mother plant and root them in plugs, and plant them all that way, and they will all be identical. They should produce the same peppers.
The other way would be tissue culture, but that is a big process and requires lots of work.
