Clean read: number of filtered sequences; clean bases: the number of sequencing sequences multiplied by the length of sequencing sequence; GC content: percentage of GC content in total base; Q30: percentage of bases with quality value ≥ 30 in the total bases; mapped reads: the number of reads mapped to the reference genome of B. napus and its percentage in clean reads; unique match: the number of reads mapped to the only location of the reference genome and its percentage in clean reads
