Significant association of increased NAE and ASE with hybrid weakness in rice

Nine rice hybrids were developed from the all possible crosses between three restorer lines (MH86, Gui99 and FH7018; as male parents) and three CMS lines (II32, TaifengA and TianfengA; as female parents). In each line, panicles at the grain-filling stage were collected from five plants grown in E3(Sanya, Hainan, China during the winter season in 2017) and mixed for RNA extractions. Three biological replicates were set.45 RNA libraries were used for sequencing on Illumina HiSeq X Ten platform and paired-end reads (PE150) were generated.
