Gamma radiation has been reported to be very effective in creating genetic variability in plants. Three varieties of Nigerian sesame were assessed for spectrum and frequency of mutation induced by Gamma radiations in M<sub>1</sub> and M<sub>2 </sub>generations. The varieties (NCRIBEN-04E, NCRIBEN-01M and NCRIBEN-03L) were treated with four different doses of gamma rays (250, 350, 450 and 550 Gy). The treated and untreated seeds (control) were sown in planting bags (under field condition) to raise M<sub>1</sub> plants. Four treatments: V1D5, V2D3, V3D2 and V3D4 (from M<sub>1</sub> plants) were selected and bulked to obtain M<sub>2</sub> populations. The results of M<sub>1 </sub>revealed four mutant fruit traits: multicarpellate capsule, multiple capsule per leaf axil, indehiscent capsule and terminal capsules. The highest frequencies of the traits in M<sub>1</sub> generation were 2.50×10<sup>-2</sup>, 9.17×10<sup>-2</sup>, 1.67×10<sup>-2</sup>and3.33×10<sup>-2</sup> respectively. The highest branching (7) was from NCRIBEN-01M, while the least (2) was from NCRIBEN-04E. The M<sub>2</sub> plants were grouped into eight M<sub>2</sub> lines. The dose range (250-550 Gy) was proved to be effective in inducing viable mutations in sesame.</p>}, number={1}, journal={Notulae Scientia Biologicae}, author={MUHAMMAD, Muhammad Liman and FALUSI, Ahmed Olamide and ADEBOLA, Matthew Omoniyi and OYEDUM, Onyedi David and GADO, Aishatu Adamu and DANG, Mohammed Chata}, year={2018}, month={Mar.}, pages={87–91} }
