Abstract

This study aimed to obtain F4 lines of red rice with high yield potential, high number of filled grains and early maturity compared to their parents (F2BC4P19-36, Fatmawati and IPB 3S varieties) through Pedigree selection. To make statistical comparison, the results of the Pedigree selection were grown together with those parents in the Experimental Farm of the Faculty of Agriculture, University of Mataram, located in Narmada, West Lombok (Indonesia), from April to August 2020. The experiment was arranged according to a Randomized Complete Block Design, with 13 treatments consisting of 10 lines resulted from the Pedigree selection and their three parents. The experiment was made in three blocks as the replicates. The results showed that the F4 IPB3S/F2BC4P19-63//Fat/F2BC4P19-63-PD3/13 line showed an average dry grain yield of 40.49 g/clump, which was significantly higher than that of the Fatmawati variety (31.53 g/clump), but it was not significantly higher than that the other parents, namely IPB 3S (35.40 g/clump) and the promising line F2BC4P19-36 (38.66 g/clump). In addition, the average filled grain number per panicle was also high while it was still in the category of early maturity. Thus, it can be concluded that the F4 IPB3S/F2BC4P19-63//Fat/F2BC4P19-63-PD3/13 line resulted from the Pedigree selection is highly potential to be bread further to develop a promising line of lowland red rice with high yield potential, high number of filled grains per panicle but early maturity.
