Abstract: An experiment was conducted at research farm, R.B.S College Bichpuri, Agra, to study the effect of mutagens on germination, plant survival, pollen viability in sesame under the laboratory condition. The result showed that the germination was reduced due to increase mutagenic dose in the treatments 20kR + o.2HA %, 20kR+ 0.2% MH, 0.2% HA, 0.2% MH and 0.2% HA + 0.2% MH except 0.1% MH. Under laboratory condition seedling vigor index was found highest in the treatment 15kR followed by 0.1% MH wet and dry control. Under field condition highest germination percentage was recorded under wet control followed by dry control and mutagenic treatments. The plant survival decreases with increase the dose of gamma rays, concentration of chemical mutagen and their combination. Highest pollen viability was observed in dry control followed by wet control and decrease with dose of gamma rays chemical mutagen and their combination treatment.
