Using induced mutants in the breedingprograms for developing superior varietiesis known as mutation breeding which usesome physical induced factors such as X-rays, Gamma-rays, β-radiation(β-particles),Neutrons, laser, electron beam, Particlesfrom accelerators, UV radiations and somechemical induced factors such as alkylatingagents, antibiotics, acridines, azides, baseanalogues and related compounds,hydroxylamines, nitrous acid, and somebiological factors :
