The present investigation was carried out at Department of Floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur during 2017-18. The experiment was designed in Randomized Block Design with Factorial Concept using vM₂ generation of three gladiolus cultivars viz. Candyman, American Beauty, Her Majesty irradiated previous year with four doses of gamma radiations 15 Gy, 30 Gy, 45 Gy, 60 Gy along with 0 Gy (control) to investigate the effect of gamma radiations. The results revealed early spike initiation (77.80 days) in variety Her Majesty. Minimum days for opening of first floret (100.86 days) were observed in var. American Beauty whereas maximum leaf abnormality percentage was observed in var. Her Majesty. Leaf abnormality percentage and morphological abnormalities percentage were found maximum at higher dose 60 Gy. Two variants from var. Candyman irradiated at 45 Gy and 60Gy and one variant from var. Her Majesty irradiated at 30 Gy were identified and isolated for changes in floret color whereas one variant was identified and isolated from var. American Beauty having variation in floret arrangement.
