  9. Mutation breeding - Wikipedia

    en.wikipedia.org/wiki/Mutation_breeding

    Mutation breeding. Mutation breeding, sometimes referred to as " variation breeding ", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
