dc.descriptionABSTRACT - The objective of this work was to identify quantitative trait loci (QTLs) associated with the traits grain yield, plant height, and flowering, as well as superior inbred lines resulting from the intersubspecific cross between 'Araguaia' (Oryza sativa subsp. japonica) and 'Maninjau' (Oryza sativa subsp. indica) rice population. A population consisting of 234 recombinant inbred lines (RILs) was assessed in two environments and genotyped using single nucleotide polymorphisms (SNPs) and SilicoDArT markers. Twenty-two QTLs accounting for phenotypic variation ranging from 3.94% to 35.36%, were identified as significant, as follows: six for grain yield, five for flowering, and eleven for plant height. New QTLs were consistently identified for height and flowering traits with the SNP marker 12_22887040, in both environments, and highlighted for assisted selection of early rice varieties. In both environments, the RIL 1572 with the greatest productivity (6,581 kg ha-1), precocity of 70 days to flowering, and the lowest plant height (90 cm) is highly recommended for integration into crosses with elite materials from the rice breeding program.
