Abstract
Successfull application of X-irradiation to obtain viable mutants affecting ray-floret characteristics of annual chrysanthemum is reported. Either strap-shaped flat rays of the control type had strikingly changed in their appearance or were entirely lacking. An interesting mutation resulted in transformation of pistillate nature of the ray florets into bisexual type. The occurrence of mutant phenotypes is genetically accounted for and the usefulness of experimental production of mutations in plant breeding is discussed.
