That's how typical plant selective breeding works. Plant a bunch of the plant, induce all the mutations you can with all the mutagens (radiation, chemicals, etc.) you can, and look for useful traits. Then use recombinant breeding techniques to try to breed just those traits back in. This has been standard practice since at least the 40s. There's very little "natural" about it.
