National Botanical Research Institute, Lucknow [From Applied Mutational Breeding for Vegetatively propagated Crops, by C. Broertjes, 1988, p. 198:] Gupta (1966) and Gupta and Shukla (1970, 1971a, b) irradiated bud wood of cvs Montezuma and Super Star and several scented cultivars. Two years after irradiation (optimum dose 40-50 Gy γ-rays) they observed mutations for flower colour and shape. In later years other cultivars were irradiated with similar results (Datta and Gupta, 1982a, 1983; Gupta and Datta, 1982). Two commercial mutants were reported, namely 'Saroda' and 'Sukumari' obtained after gamma irradiation of budwood of 'Queen Elisabeth' and 'America's Junior Miss' respectively.
