“…To improve yield, we have explored various methods, including conventional cross-breeding with short-lived and high-yielding "Inpari-4" white rice variety (Limbongan et al 2019), and plant mutation using the heavy-ion beam (Sjahril et al 2020;Riadi et al 2018). Consequently, we have opted for conventional breeding to produce new varieties, which began with forming new populations through crossings to combine important agronomic characters from different parents.…”

Abstract. Limbongan YL, Driyunitha, Sjahril R, Riadi M, Jamaluddin I, Okasa AM, Panga NJ. 2021. Heritability and genetic advancement on agronomic characters of Toraja red rice x Inpari-4 white rice genotypes. Biodiversitas 22: 3446-3451. Determination of genetic diversity, heritability, and genetic advance on specific agronomic characters of cross-breed red rice genotypes (Toraja red rice Pare Lea’ x Inpari-4) was done in Tallunglipu, North Toraja, South Sulawesi, Indonesia. The experiment was designed using a randomized complete block design. Twenty-one days old seedlings were transplanted following the system of rice intensification practices. Selection was conducted at F2 as a novel method to speed up genetic advancement and ensure progeny production with desired agronomic traits. Results indicated existence of a considerably high level of diversity among genotypes tested, where the highest value for genetic advance was observed in filled-grain weight per hill of F2 plants (983.890), followed by plant height (335.124), and filled-grain weight per hill of F1 (306.645). The highest estimate of broad-sense heritability was recorded in 1000-grain weight (0.915), number of productive tillers (0.788), plant height (0.765), flag leaf length (0.705), filled-grain weight per hill (0.688), and harvest age (0.594). Genetic advance of agronomic characters between genotypes varied from 1.631-38%, where the highest estimate was recorded in filled-grain weight per hill (38%) and plant height (24.648%). The above-mentioned characters could be used for selection in further rice breeding programs to obtain plants with superior genotypes.

“…The highest number of panicles was in PB-A (41 plants) with a frequency of 20.9%, PB-C reached 22 plants with a frequency of 10.58%, and control reached 5 plants with the frequency of 11.9%. This was illustrated by the finding of Sjahril et al (2020).…”

Abstract. Okasa AM, Sjahril R, Riadi M, Mahendradatta M, Sato T, Toriyama K, Ishii K, Hayashi Y, Abe T. 2021. Evaluation of Toraja (Indonesia) local aromatic rice mutant developed using heavy-ion beam irradiation. Biodiversitas 22: 3474-3481. The aromatic local Toraja rice "Pare Bau" has a good grain quality and aroma. However, it has some disadvantages, including a late heading and low yield for a modern farming system. This study aims to evaluate and select early heading as well as high yield mutant lines induced by heavy-ion beam irradiation. Furthermore, dry seeds of Pare Bau were irradiated with Argon-ion (300 keV/?m) and Carbon-ion (30 keV/?m) at RI-beam factory, RIKEN Nishina Center, Japan. The germination percentages of the M1 seeds were 49% for Pare Bau irradiated with Argon-ion (PB-A), 53% for Pare Bau irradiated with Carbon-ion (PB-C), and 70% for the Control. The 13 PB-A and 13 PB-C M1 plants were selected, and the seeds were sampled in the paddy field of Hasanuddin University (20 m asl.), Makassar. During the following planting season, the M2 generation plant was examined in Enrekang District (650 m asl.), South Sulawesi, Indonesia. Based on the early heading and a larger number of panicles, the 18 PB-A and one PB-C M3 line were selected from a total of 404 M2 survival plants. The selected lines and control were grouped into seven clusters based on the quantitative phenotypic traits, indicating the existence of genetic variability. The plant yield was significantly correlated with plant height, the number of tillers, the number of panicles, as well as grain weight per panicle, which showed that these traits are good criteria for selection.

“…Gamma ray radiation has been shown to produce several changes in plant morphological and biochemical characters. Gamma ray irradiation had a significant effect on the morphology of black rice plants [1], the production of mutant Fukuhibiki rice plants which increased from 1.2% to 22.5% [2] and shorter harvesting age in Toraja local red rice mutant genotype [3].…”

Rice (Oryza sativa L.) is an important cereal crop for human nutrition. Labuhanbatu Regency is one of the regencies in North Sumatra Province with a local type of rice, namely Ramos local variety rice. It usually adapts well to a specific environment where it grows larger, having a pleasing aroma and eating quality, but it has weaknesses such as very long growth duration, susceptibility to lodging, unresponsive to fertilizer, and low yield. The induction of gamma-ray irradiation on Ramos is expected to increase diversity. This study aimed to determine the growth response of Labuhanbatu Local Rice with Gamma Ray Irradiation in M1 Generation. The research was conducted in PAIR BATAN and Labuhanbatu University Agrotechnology Experimental from May 2021 to September 2021. This study used a non-factorial randomized block design with three replications. The doses used were 0 (control), 150 Gy, 200 Gy, 250 Gy and 300 Gy. Parameters observed were the plant height and the number of tillers on the M1 population. Data analysis showed that gamma irradiation was significantly different from the plant height. Irradiation caused a marked decrease in the 300 Gy irradiation treatment.
