There is a big difference between Selective Breeding vs Genetic Modification
Yes, in traditional selective breeding one would typically expose the plant to various mutagenic chemicals or radiation to generate mutations, both SNPs and gross chromosomal rearrangements, and select for those plants that have traits of interest, usually agronomic traits such as herbicide tolerance . In genetic modification the transgene (generally a chimera consisting of DNA sequences of different origins but known functions, eg herbicide tolerance) is fully characterised and once inserted into the plant genome it's location can be mapped precisely.
