Not to beat a dead horse but do you know how we get/got novel variation in crops before targeted DNA technology? It mostly wasn’t wild germpasm unless you happen to work with a crop with large amounts of historically documented pools, e.g. corn and wheat. No, most historical breeding programs use mutagens, either chemical or sometimes radioactive, to cause novel variation, grow the seed, see what looks interesting and not too weird, and cross it back into your gene pool. GMOs are significantly less mad science-y than what they replace.
