Rice tiller angle is an important agronomic trait that contributes to crop production and plays a vital role in high yield breeding. In this study, a recombinant inbred line (RIL) population derived from the cross of a glabrous  tropical japonica  rice D50 and an  indica  rice HB277, was used to investigate quantitative trait loci (QTLs) controlling rice tiller angle. Two major QTLs,  qTAC8  and  qTAC9 , were detected. While  qTAC9  mapped with a previously identified gene ( TAC1 ), using a BC 2 F 2  population  qTAC8  was mapped to a 16.5 cM region between markers RM7049 and RM23175. Position of  qTAC8  was narrowed to a 92 kb DNA region by two genetic segregating populations. Finally, one opening reading frame (ORF) was regarded as a candidate gene according to genomic sequencing and qRT-PCR analysis. In addition, a set of four near isogenic lines (NILs) were created to investigate the genetic relationship between those two QTLs, and one line carrying  qTAC8  and  qTAC9  presented additive effect of tiller angle, suggesting that these QTLs are involved in different genetic pathways. Our results provide a foundation for the cloning of  qTAC8  and genetic improvement of the rice plant architecture.
