Gamma ray–induced mutagenesis was applied to Oryza sativa seeds to enhance weed resistance and identify the optimal irradiation dosage. Seeds were irradiated at 250 Gy and 300 Gy using the Obi-Servo Sanguis Gamma Irradiator, while non-irradiated seeds served as control. Results showed germination rates of 53.33%, 66.67%, and 86.76% for control, 250 Gy, and 300 Gy, respectively. Only irradiated seeds developed roots, with the 250 Gy group reaching 1.8 cm and the 300 Gy group 2 cm by Day 2. The 300 Gy dosage produced the highest germination and root growth, indicating successful induction of beneficial mutations enhancing vigor and weed resistance.
