Development of new cultivars through conventional or modern techniques have been a great demand in commercial floriculture. New colour, earliness, stem length, number of flowers, plant architecture, resistance to abiotic and biotic stress, productivity and vase life are the main attributes required in new cultivars. Mutation breeding is an established method for crop improvement and has played a major role in the development of many new flower colour/shape mutant varieties in ornamentals. A spontaneous mutant was observed in a carnation at Floriculture Center of VCSG Uttarakhand University of Horticulture and Forestry, Bharsar ,Uttarakhand during 2013.The mother plant of the mutant was variety ‘Tempo’. Initially plant showed sectoral chimera on flower but latter on mutant plant developed flower having change in whole colour of flower from creamish white to deep pink on few branches.
