“…A negative effect of higher doses or concentrations of mutagens on germination percentage in rice was determined by Gowthami et al (2017) citing disruptions at the cellular level (physiological or physical level) and chromosomal damage as possible causes. A similar finding was also made by Naibaho et al (2021), who stated that the highest level of rice germination occurred at radiation doses of 100-400 Gy and the lowest at a dose of 700 Gy, while there was no germination at doses of 800 Gy and above. The results showed that gamma irradiation had greater impact on seedling growth compared to germination process.…”

“…This reduction of growth could be explained by the effects of irradiation on the signalling pathway of growth regulatory factors and cell oxidation at the highest irradiation doses (Wi et al, 2007). Naibaho et al (2021) also stated that plant height decreased with higher irradiation doses with reduction up to 46.51% at 600 Gy. The efficiency of mutation breeding will be higher if the optimal dose of radiation is determined, which will lead to an increase mutation frequency and will not significantly threaten the survival and reproduction of plants (Hong et al, 2022).…”

One of the major challenges that plant breeders face in the 21st century is food safety for growing human population coupled with extreme climate changes. Accordingly, the most important breeders' goal is to find appropriate methods in response to these challenges in order to create high-yielding varieties resilient to abiotic and biotic stressors. The aim of this study was to determine optimal doses of gamma irradiation in two wheat and one barley varieties and to apply the identified doses for development of mutant populations. Wheat and barley varieties showed different reactions to applied doses of gamma irradiation. Wheat varieties had germination rate over 90% at all applied doses while barley seeds showed to be more susceptible to gamma irradiation. Gamma irradiation had greater influence on seedling height which was clearly demonstrated by growth reduction with increasing radiation doses. ANOVA showed a significant difference between genotypes, applied doses of gamma radiation as well as genotype by doses interaction for seedling height. At highest dose of 600 Gy, the reduction of seedling height was 94.6%, 96.5% and 96.8% in Simonida, Rudnik and NS 40S, respectively. The irradiation doses that resulted in seedling growth reduction by 50% (GR50) were 210 Gy for barley Rudnik and wheat NS 40S, and 310 Gy for wheat variety Simonida. Identified doses were used for the irradiation of 2000 seeds of each variety in order to produce mutant populations that will be further used in a breeding program for development of varieties with increased resilience to climate change.

“…The rice seeds of the Sidikalang cultivar (M3) used were generated by Naibaho et al (2020) with an LD-50 value of 586.45 Gy, so the radiation dose used was 0 Gy, 200 Gy, 400 Gy, and 600 Gy.…”

Abstract. Naibaho D, Purba E, Hanafiah DS, Hasibuan S. 2023. Improvement of morphology, biochemical characters, and molecular changes of local upland rice cv. Sidikalang M3 generation through induction of gamma-ray irradiation. Biodiversitas 24: 200-207. Upland rice cultivar Sidikalang is one of the local upland red rice cultivars of North Sumatra, which has the potential to be developed. However, this rice has limited planting area due to factors such as its higher plant height and long duration compared to other rice cultivars. Plant characteristics can be improved through induced mutation using gamma-ray irradiation. This study aimed to determine gamma rays' effect on changes in morphological, biochemical, and molecular characters and to obtain a superior Sidikalang cultivar mutant plant M3 generation. Observations of morphological changes were carried out quantitatively and qualitatively, biochemical analysis (amino acid content) was done using a High Performant Liquid Chromatography analyzer, and molecular analysis was performed using Random Amplified Polymorphism DNA markers. The results showed that 600 Gy gamma-ray irradiation improved quantitative morphological characters (shorter plant height, higher number of tillers and panicles, faster panicle release age) and qualitative morphological characters (flag leaf angle in dwarf mutants became upright) compared to no irradiation. 400 Gy gamma-ray irradiation also increased almost all amino acid content compared to no irradiation. The presence of polymorphic bands in the M3 generation Sidikalang cultivar mutant plant evidenced changes in morphological and biochemical characters.
