Gamma rays (from cobalt 60) is generally used for induced mutation in crop plants. Gamma rays are ionizing radiation and used in inducing mutations in seeds and other planting materials such as cuttings, pollen, or tissue-cultured calli. X rays are used to induce genetic mutation. Ultraviolet (UV) light has strong genotoxic effect to induce mutations for developing high genetic variability in yields, early maturity and other characters in crops. Related Theory Non-ionizing radiation is longer wavelength/ lower frequency lower energy. While ionizing radiation is short wavelength/high frequency higher energy. Non-ionizing radiation includes the spectrum of ultraviolet (UV), visible light, infrared (IR), microwave (MW), radio frequency (RF), and extremely low frequency (ELF). Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements. Ionizing Radiation has sufficient energy to produce ions in matter at the molecular level.
