Humans have been modifiying the genes of plants for over ten thousand years. Only difference now we can purposely target genes.

We’ve been gene editing crops a long time, it’s not proven itself especially harmful beyond the specific ones engineered to resist herbicides allowing greater use of those things, which this doesn’t sound like a case of. Food crops are very divergent from wild ancestral plants regardless of the method used to achieve that, if you’re finding farm-type wheat out in the wild that probably indicates an ecological problem regardless of if they’ve been gene edited or not.
