Multi-Year QTL Mapping and RNA-seq Reveal Candidate Genes for Early Floret-Opening Time in Japonica Rice

Floret-opening time (FOT) refers to the between florets opening and closing within a day, is crucial agricultural trait for reproductive development, thermal tolerance hybrid breeding in rice. However, little known about genetic basis genes controlling FOT Here, we report mapping transcriptome analysis of japonica rice cultivar G23. Combining QTLseqr GradedPool-seq (GPS) methods, located major quantitative locus (QTL), qFOT6, on chromosome 6 multiple years under different environments. Integrating RNA-seq analysis, selected 13 potential candidate qFOT6 interval that might be associated with Taken together, our work uncovers QTL rice, thus providing invaluable clues breeding.
