Gladiolus ‘White Prosperity’, bulbs was induced by gamma rays, Dry Ethyl Methane Sulphonate (DEMS) and soaked Ethyl Methane Sulphonate (SEMS). The treatments consisted of 2 Kr, 4 Kr, 6 Kr, 8 Kr, 10 Kr and 12 Kr of gamma rays; 0.25%, @ 0.5%, @ 0.75%, @ 1.0% and @ 1.25% of DES; 0.25%, @ 0.5%, @ 0.75%, @ 1.0% and @ 1.25% of EMS and control (untreated) in first year. In the second year we take produced corm as seed and observed the changes in different characters of the crop with control seed. Different concentrations of EMS and different level of gamma radiations had a major effect on sprouting and it significantly delayed the emergence of sprouts. About one third decreases in plant height along with reduction in number of leaves per plant and number of cormles per corm was observed in treated plants. In general, the treated population had manifested reduced expression than the control (untreated population) for most of the characters. After the observation it found that maximum plants height was observed in control while minimum height observed in the treatment with Gamma Rays 12Kr while maximum number of leaves and number of shoot per corm were recorded in treatments with Gamma Rays 2Kr and SOAKED EMS @ 0.25%) respectively. Maximum number of spike per plant was recorded in treatments with Soaked EMS @ 0.25% while minimum number of spike per plant was recorded in T0 (Recommended dose of nutrients through chemical fertilizers). The gladiolus plants could not survive in treatments of gamma rays and its combination with EMS. On the basis of above observations, it may be concluded that 0.25 to 0.50 per cent dry and soaked EMS doses are suitable for inducing mutation in gladiolus.
