Abstract

In this study, quantitative trait loci (QTLs) for flag leaf angle and other traits were identified using rice double haploid population (DH population) derived from Cheongcheong × Nagdong. A total of 9 QTLs were identified for the four traits located on three different chromosomes of rice and analysis of interaction among the QTLs revealed additive effect for the leaf angle and epistatic main effect for decreasing flag-leaf angle. When a physical map was generated based on the detected QTLs, nine genes for qFA4, two genes for qFA11, seven genes for qPE3, and six genes for qCC11 were identified. These results provide a foundation for the functional characterization of the gene underlying the pleiotropic effects of qFA4 and for genetic improvement of the plant architecture and yield potential of rice.
