“…Lee et al (2010) irradiated cuttings of the Chrysanthemum cultivar Beakma and found a mutant that did not form a hollow stem when grown in high summer temperatures, leading to plants with stronger stems that are easier to handle. A Gerbera jamesonii mutant that was tolerant to powdery mildew was found by Ghani and Sharma (2019). X-ray irradiation restored male fertility in Dianthus caryophyllus (Sagawa and Mehlquist, 1959); however, Biswas and Biswas (2006) were able to induce partial sterility in Ornithogalum virens.…”

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.

“…For instance, gamma irradiation has been found to be effective in controlling powdery mildew, gray mold and downy mildew on cucumbers (Faris et al, 2016). The use of gamma irradiation has been shown to be effective in controlling various fungal diseases in other crops such as gerbera (Ghani and Sharma, 2019;Serrano-Fuentes et al, 2022).…”

Plant diseases pose a significant threat to global food security, leading to substantial yield losses and economic damage. In recent years, irradiation technology has emerged as a promising approach to enhance plant disease resistance. Gamma irradiation, a well-established technique, has been utilized for approximately 60 years to develop new plant varieties with improved resistance to pests and diseases. X-ray is another form of ionizing radiation, has also shown the potential in enhancing plant disease resistance. UV light, including UVB and UVC radiation, has been effective in eliminating microorganisms by damaging their DNA. Electron beam irradiation, a non-ionizing form of radiation, has been investigated for its impact on plant disease resistance. However, the implementation of irradiation technology in agriculture faces challenges such as public perception, regulatory barriers and cost-effectiveness. This review article highlights the advances in irradiation technology for plant disease resistance. It emphasizes the potential of gamma irradiation, X-ray gamma irradiation, UV light, UVB, UVC and electron beam in enhancing plant disease resistance.

The breeding of resistant, high-yield, decorative ornamental plant varieties may be impacted by climate change in the future. The use of radiation induces mutations in plants, thereby increasing the genetic variability of plant species. Rudbeckia hirta has long been a very popular species in urban green space management. The goal is to examine whether gamma mutation breeding can be applied to the breeding stock. Specifically, differences were measured between the M1 and M2 generations, as well as the effect of different radiation doses belonging to the same generation. Morphological measurements showed that gamma radiation has an effect on the measured parameters in several cases (larger crop size, faster development, larger number of trichomes). Physiological measurements (examination of chlorophyll and carotenoid content, POD activity, and APTI) also showed a beneficial effect of radiation, especially at higher doses (30 Gy), for both tested generations. The treatment was also effective in the case of 45 Gy, but this radiation dose resulted in lower physiological data. The measurements show that gamma radiation has an effect on the Rudbeckia hirta strain and may play a role in breeding in the future.
