Abstract
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.
