The corms of gladiolus cv. PINK BEAUTY were treated with gamma rays (0, 3, 6, 9 kR), EMS (0. 0.2, 0.4, 0.6 %) both alone and in combination including control i.e. untreated. Different vegetative, floral and corm parameters were recorded. The days taken for sprouting of corms were delayed after treatment with gamma rays and recorded maximum at 6 kR + 0.2 % (26.78 days). Duration of sprouting was decreased by EMS and was observed to be maximum at 3 kR gamma rays (100%). 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 0.2 to 0.6 per cent EMS doses are suitable for inducing mutation in gladiolus.
