Haenchen and Gelfert (1978) studied no less than 5819 rose varieties, marketed from 1937 until 1976, and found that 865 developed from bud mutations, 289 of which were climbers.....Several examples of "sport families" are presented, such as that of the cultivar Columbia (from 1917) with the greatest number of sports, namely 79 in 1978.

Chan (1966) irradiated five cultivars (Peace, Queen Elisabeth, Better Times, Baccara and Tropica) and found several mutations that affected flower colour and growth habit after X-ray doses of 70-80 Gy or higher.

James (1983) reports on two induced mutants, 'Paula' from 'Queen Elizabeth' and 'Pink Hat' from an unnamed R. floribunda. Both were obtained as early as the fifties by γ-irradiation of actively growing terminal buds..
