Abstract
Mutation breeding is one of the fasted and efficient methods of generating genetic variability in crop plants. Several mutagens including chemical mutagens like EMS and physical mutagens like gamma radiation, fast neutrons, ultrasounds etc., have been frequently used in generation of mutant lines in crop plants. In sunflower also, mutation breeding has been successfully utilized not only in generating mutant lines but also has led to the development of mutant sunflower varieties which has been enlisted in mutant variety database (MVD). Along with phenotypic traits like plant height, number of seeds, seed weight, seed size, head diameter etc., the oil quantity and qualities can also be enhanced through mutation breeding. Therefore mutation breeding can be effectively utilized in sunflower as well as other crop improvement programmes.
