“…Rice's plant height and seed fertility percentage declined with linear trend along with enhancement of gamma radiation doses starting from 100 Gy to 350 Gy (Sasikala & Kalaiyarasi, 2010). In addition, the application of 200 Gy gamma ray radiation created genetic changes in black rice in term of plant height (Warman, Suliansyah, Swasti, Syarif, & Alfi, 2015). This result was in line with other experiment which revealed that 200 Gy gamma ray decreased the plant height of Cempo Ireng black rice (Masruroh, Samanhudi, Sulanjari, & Yunus, 2016).…”

Black Rice is rice producing anthocyanin in high intensity and popularly consumed as functional food. Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

“…The plant height and productive tillers being essential agronomic characters and important identity of the genotype. Reference [26] reported that plant height characters being influenced by one or two allele groups, of which one allele controlled the semi-dwarf, while the other one controlled the plant height character. The Sriwijaya/N148+ crossbreed height averagely 118.5 cm, while the Sriwijaya/IR7858-1 crossbreed height averagely 109.7 based on the SES IRRI [19], while the ideal plant characteristics according to [27] for the plant height averagely 115-120 cm.…”

Variety assemblings for higher yield capacity of upland rice which tolerant to drought stress and highly adaptable to climate change has been needed to support the effort to increase both rice yield and the upland rice field extensification. This research aims to screen and identify an agronomic character of upland rice lines as the result of recurrent selection to a seedling stage on the drought stress. Materials were 180 rice lines as the result of recurrent selections from two local varieties Sriwijaya and Bugis with other two drought tolerant lines IR7858-1 and N148+. Twenty seeds each genotype were seeding in seed pods adjusted with stripe check such Situbagendit and Inpari 6 as tolerant and susceptible lines respectively. Drought stress treatment had conducted in a week, began at two weeks seedling age with a scoring value 0-9 (SES IRRI), at the same time were taken sample soil to measure the soil water content was done at a depth of 20 cm. Then, the crops were watered again to observe the recovery capacity of the crops, with the scoring 1-9 (SES IRRI). Anatomically stomatal proximation was observed for both susceptible and tolerant rice lines. The selected lines would transplant in the field to record the yield capacity and other agronomic characters. The SES screening resulted in 53 tolerant lines, 99 moderate tolerant, and 28 susceptible to the drought stress which had the soil water content ranged from 11.9 to 12.7 percent. Anatomic stomatal observation showed that the stomatal structure and density of susceptible lines were closer and more than tolerant lines. The highest percentage of filled grains showed by the intercross line Sriwijaya/IR7858-1 about 77.4 to 85.1 percent with averagely 80.7 percent, which was a high category with the scale of 3 SES IRRI. The selected drought stress lines with better agronomic character would continuously test to know the yield capacity in the environmentally specific location.

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.
