The aim of this study was to obtain superior lines that had higher yields and shorter harvesting ages than their parents. The research was conducted in Saribaye Village, Lingsar, West Lombok Districts, from February to July 2020. The study used a Single Plant Design with the treatment of the M1 G16 mutant population at irradiation doses of 200 Gy, 300 Gy, 400 Gy and 500 Gy and parent (G16 line) as a control. Each treatment planted 200 seeds while the control was repeated three times. The variables observed included the number of productive tillers (saplings), panicle length (cm), number of filled and empty grains per panicle (grains), age of harvest (HSS), weight of 100 grains (g) and weight of filled grain per clump (g). . The value of genetic variance is calculated based on the reduction of phenotype variance with environmental variation (Mangoendidjojo, 2007). Determination of the potential for superior line candidates is done by setting the selection limit value (Xs) according to Kuswanto and Waluyo (2012). The selected genotype is a genotype that has a production value of more than Xs and an age of less than Xs. The results showed that there was an increase in genetic variance due to gamma ray irradiation treatment. A total of three mutant genotypes were successfully selected as candidates for superior strains, namely M1G16-9D3, M1G16-14D3, M1G16-27D3. The three mutant genotypes have the opportunity to be further developed into superior varieties with high yield potential and early maturity.

“…Carbohydrates and protein can both be found in abundance in red rice. Grain yields have remained unchanged despite several attempts to increase rice output [7]. Lowland rice is farmed in flooded areas, either with natural or artificial water sources.…”

The research experiment conducted on the farmer paddy field in Ranomeeto village, District of South Konawe, Indonesia from January to May 2022, to evaluate the yield attributing characters and the grain yield in some new promising lines or cultivar of red rice. The red rice lines tested are GS12-1, GS12-2, GS16-1, GS16-2, GS44-1, and control variety Inpari-33, were laid out and arranged in field using randomized complete block design (RCBD) in three replications. The parameter measured were plant height, tiller density, productive tiller density, flowering time, harvesting times, panicle length, panicle density, filled grain percentage, 1000-grain weight, and grain yield. Differences between promising lines of red rice were found to exist when data on various yield-attributing features and grain yield were analysed. GS16-1 (89.37 cm) was the tallest plant and GS12-2 the shortest (72.74 cm). GS16-2 had the longest panicle (25.96 cm) and most grains per panicle (146.62). GS44-1 full grains, 1000-grain weight, and grain yield were highest. G12-1 lines had the most productive tillers, days to flowering, and harvest. Tiller number and productivity are positively correlated (0.908**). Tillers, productive tillers, and full grains percentage positively affect grain yield per plant.

“…Several programs have been implemented to maintain rice sustainability [5] and to increase rice stock levels through increase production capacity [6][7][8][9], lowering level consumption, and consuming local food as sources of carbohydrate [4], as well as expanding planting areas. Although numerous attempts have boosted rice production [10,11] grain yields have remained stagnant [12].…”

Efforts to develop upland rice need to be supported by plant breeding programs by assembling superior upland rice varieties. Eight advanced promising lines developed through a hybridization breeding program and two check varieties were used to study. The study conducted in Langgea Village (4°3’24”S and 121°27’59”E), Ranomeeto District, South Konawe Regency, Southeast Sulawesi. The experiment arranged in a split-plot design using randomized complete block (RCB) and three replications. Shade treatments arranged as main plots and the different of upland rice promising lines as subplots. The parameters observed were included vegetative and generative character. The results showed that the genotypes significantly differed in grain yield and yield attributing traits. The estimation of genetic parameters of some upland rice promising lines for grain yield and yield attributing traits indicated that total grain per panicle and leaf area had high both genotypic and phenotypic coefficient variance. There were genotypic diversity values on the appearance of some upland rice promising lines at a low light intensity, which had the highest value on the total grain per panicle (282.13) and the lowest value on the grain weight per clump (1.02).
