Description
The research program for advanced radiation technology was planned in 1987 by JAERI taking a leading part, and Takasaki Ion Accelerators for Advanced Radiation Application (TIARA) was completed in 1993 as a first facility in the world for the exclusive use for materials science and biotechnology. The characteristics of ion beam breeding and its expectation for the future is stated. It consisted of characteristics of ion beam-induced mutation, DNA damage and mutation induction by ion beams and expectations of the ion-beam breeding in plants. Nagatomi et al. (1995) first showed the most important data, i.e. the mutation spectrum of flower color by using chrysanthemum cv.Taihei (pink color). The flower color mutation frequency induced by carbon ions was approximately half of those induced by gamma ray. It is obvious that double-strand DNA breaks induced by ion beams are less reparable than those by γ-ray irradiation. Because ion beams deposit high energy on a target densely and locally as opposed to low LET radiation. Ion beams as a new mutagen is expected for making new commercial varieties even in plants for which recombinant DNA techniques can not be applied. (S.Y.)
