“…Laju dosis iradiasi adalah jumlah dosis yang diserap per satuan waktu (rad per detik atau Gray per detik) (Abdelnour-Esquivel et al, 2020). Dosis tinggi umumnya mengakibatkan kematian, sedangkan dosis rendah umumnya hanya menyebabkan perubahan fenotipe tanaman yang tidak normal dan bersifat reversible (Abdelnour-Esquivel et al, 2020;Gajbar et al, 2021;Hasan et al, 2020;Kant & Chakraborty, 2021;Kato et al, 2020;Mohammed et al, 2018;Ocloo et al, 2017). Sensitivitas terhadap radiasi dapat diukur berdasarkan nilai LD (lethal dose), yaitu dosis yang menyebabkan kematian populasi tanaman yang diradiasi adalah penentuan LD 50 (50%) (Njoroge et al, 2022).…”

The widespread use of mutagenesis for plant genetic improvement can be explained by a number of factors, including the fact that new varieties can be developed in a shorter time than conventional breeding methods and that transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens that are often used in plant mutagenesis techniques and are safe for human health because there is no environmental risk in the induced generations. The method used in this paper is by grouping articles according to their relevance to the subject and year of research, and finally managing the explanatory structure. Journal articles for the period 2012 to 2022 were searched using keywords: breeding, mutation, mutagen, rice, and gamma iridation. The selection of selected articles comes from the PubMed, Elsevier, and Springer web sites. This paper integrates the available data on the effects of mutation breeding of plant varieties in different countries and addresses the potential of gamma irrigation as a flexible and practical approach that can be applied to rice crops and an appropriate selection method.

Mutation breeding is a significant means of increasing breeding efficiency and accelerating breeding process. In present study, we explored a new method for mutations inducing in rice (Oryza sativa L.) by using direct current electrophoresis bath (DCEB). The results showed that 20 mM NaCl solution is the optimal buffer, and the mortality of rice seeds followed an upward trend with increasing voltage and processing time of DCEB. By exploring the mutagenic effects of γ-irradiation and DCEB on seed vigor and physiological damages, we found that the physiological damages induced by DCEB on seed vigor were significant compared with that by γ-irradiation. We screened two mutants with low filled grain percentage and one mutant with abnormal hull from the M2 generations. These three mutants were confirmed to be authentic mutants based on 48 SSR markers followed by the protocol NY/T 1433–2014. Whole-genome resequencing detected a total of 503 and 537 polymorphisms in the two mutants, respectively, and the DCEB mutagenesis induced mainly InDel variants, while the exon region of mutant genes occupied a large proportion, especially the SNP variants, which occupied about 20% of the mutation sites in the exon region.

Black rice is a food that can be consumed as a functional food ingredient. Black rice has not been widely cultivated while the seeds are not commercially available. Besides, black rice also has several weaknesses such as longevity, high plant habitus and low production. This study aims to test black rice accession using gamma ray irradiation in the M1 generation. The research was conducted in January - April 2020 in the experimental rice fields of Cineam District, Tasikmalaya Regency. The materials used are black rice seeds (PH2, PH3, PH5, PH7 and PH8). The treatments tested were 5 black rice accession (PH2M1, PH3M1, PH5M1, PH7M1 and PH8M1) that was irradiated with gamma rays (200 Gray) and 0 Gray as control. The results showed that irradiated and non-irradiated rice growth gave different responses. All black rice accessions after irradiation experienced stem shortening and decreased number of filled grains. Accession PH 7 showed shorter flag leaves, number of productive tillers and fewer total tillers after irradiation. Meanwhile PH8 showed the number of productive tillers and total tillers were more and the panicles were shorter after irradiation.
