Effects of Gamma-ray Irradiation on Radio Sensitivity in Oat (Avena sativa)

Abstract: -This study examined radiation damage and the optimal gamma-ray dose for mutation breeding in oat (Avena sativa L. cv. Samhan). The seed germination rate decreased as the dose increased over 500 Gy. The median lethal dose (LD50) was approximately 392 Gy. The median reduction dose (RD50) for plant height, tiller number, root length, and flash weight was 411, 403, 394, and 411 Gy, respectively. The optimal dose of gamma irradiation for inducing oat mutation appears to be in the range 300-400 Gy. We performed the… Show more
