The topic of investigation revolves around the use of electron beam as a mutagen to induce variability in the rabi sorghum population known as TSG-98 (Muguthi). The study, conducted over a span of three years, aimed to evaluate the mutagenic sensitivity and effectiveness of different doses of electron beam irradiation on the germination, plant survival, and chlorophyll mutations in the M1 and M2 generations of TSG-98. The results revealed a dose-dependent reaction, with lower doses being more effective and efficient in inducing viable mutations.
