Most of what I've read on this subject, from the scientific community, suggests that gene editing is safer than breeding for characteristics, because it's more targeted and controlled. If the concern is long-term viability of a species, then plants whose genes have been carefully edited are subject to all of the same evolutionary selection pressures as plants that have been altered through breeding. Note that for instance the heavily-selection-bred Cavendish banana is currently facing possible extinction due to its susceptibility to a fungus. So on the one hand here you have exactly the problem you're worried about with gene-edited crops, and meanwhile gene editing is a possible solution to the problem. I regret that I'm not well-enough versed in the science of this subject to communicate it better.
