“…Leaf morphology was affected in Weigela and Ribes sanguineum, which, in the case of the latter, led to the cultivar Oregon Snowflake (Contreras and Friddle, 2015;Duron, 1992). Smilansky et al (1986) observed a decrease in rose petal number and flower size after EMS treatments of cuttings. Flower color mutants that had lower cyanidin and pelargonidin concentrations were also found.…”

The promising possibilities of mutation breeding in ornamental plants have led to a great interest in effective mutagenic treatment protocols for various species. This review discusses mutagenic treatments of a large number of ornamental genera, the advantages and disadvantages of various techniques, and the possibilities of improving the associated protocols. A number of nontargeted mutagenesis methods are available, ranging from chemical treatment with alkylating agents to irradiation with X-rays, gamma rays, and neutron or heavy ion beams at various doses. These are all relatively inexpensive and have been proven to be effective mutagens in a large number of diverse species. Genetic engineering, however, remains mostly impractical for many ornamental breeding operations because of the high cost and lack of knowledge necessary to successfully transform and regenerate ornamental crops. Of the available nontargeted mutagens, irradiation with gamma rays is still the most popular. It provides high consistency compared with chemical mutagens, albeit at a seemingly lower mutagenic efficiency. Changes in the radiation dose rate may increase the efficiency, although chronic irradiation over a longer period causes fewer deleterious mutations than the commonly used acute irradiation protocols. Heavy ion beam irradiation may also provide highly consistent mutation induction at higher efficiencies because of the high particle energy associated with these treatments. There are also opportunities to improve chemical mutagenesis. Although the required knowledge of specific gene functions in many ornamentals is still lacking, combination mutagenesis with ethyl methanesulfontate with genetic screening in a process known as TILLING (Targeting Induced Local Lesions IN Genomes) may lead to a powerful mutation breeding tool in the future. Mutation breeding is still very useful, and many opportunities are available to improve the existing methods.

“…Other variations in Rosa were restoration of fertility and changes in color (orange, pink, etc. compared with red in the original cultivar), possibly because of changes in cyanidin and pelargonidin content (Smilansky et al, 1986).…”

“…Inducing mutation in combination with in-vitro culture methods is now being considered as an effective method for plant improvement in several vegetative propagated crops such as flowers and ornamental plants. Many pieces of research on invitro mutagenesis rose by gamma-ray irradiation had been published (Smilansky et al, 1986;Datta, 1997;Arnold et al, 1998;Mohan Jain, 2006;Chakrabarty and Datta, 2010;Kahrizi et al, 2011;Baig et al, 2012;Aamir et al, 2016;Bala and Singh, 2016). Many new rose varieties were created in the world and developed for commercial production by the use of in-vitro mutation-assisted breeding techniques, typically three mutant rose varieties: Rosmarin, Yulikara, and Rosanda (Jain, 2006).…”

Rosa hybrida L. var. Lửa has been one of the most important roses for a long time and is most often used for ornamental purposes in Sadec city, Dong Thap province. The study aimed to induce variation through in-vitro gamma-ray irradiation in the rose variety ‘Lửa’ for further improvement in rose breeding. In-vitro single node cuttings (25 in-vitro cuttings per treatment with four replications) were irradiated with different doses of γ-rays (0, 5, 10, 15, 20, 25, or 30 Gy) using a 60Co source (India) at Da Lat Nuclear Research Institute. The γ-irradiated explants were then cultured aseptically on Murashige and Skoog’s basal medium supplemented with 1.0 mg/L BAP to induce multiple shoots, shoot proliferation, and acclimatization at Division of Vegetables, Flowers and Landscaping of Southern Horticultural Research Institute (SOFRI). The LD50 dose was determined at 20 - 25 Gy treatments and these doses affected the multiplication rate, growth in-vitro, and ex-vitro survival rate. Three types of mutants with altered or novel flower color in comparison to the original flower color were isolated, such as Type 1 with orange-pink (Red 52C), Type 2 with pink (Red 54B), and Type 3 with Red 45AB with Red 54B bicolor.

“…Frequent studies reported the ionizing radiation effects on the shape and form of the floral organs: Smilansky et al (1986) working on Rosa spp., Soedjone (1989) on Begonia semperflorens, Datta (1990) on Rosa spp., Banerji et al (1996) on rooted cutting of Chrysanthemum morifolium, Khalaf (2008) on Amaranthus caudatus and El- Shennawy et al (2011) on Encelia farinosa. They concluded that these changes in flower color might be attributed to the effect of radiation treatments along with the temperature and light influence on the development of pigments.…”

The purpose of this study was to study the effect of gamma irradiation and in vitro culture on mutation induction of flower color in Catharanthus roseus. A number of plants were regenerated from irradiated internode explant. Tow cultivars from previous study Rosea and Alba, and four doses of gamma irradiation (0.0, 0.5, 0.75 and 1.0 Gy) were applied. Obtained results indicated that both 0.75 and 1.0 Gy irradiation doses were the most effective in inducing mutation in flower shape and color, while the dose of 0.5 Gy was effective in inducing mutation in leaf form.
