Production of doubled-haploid(DH) selfed-progenies in ‘Banpeiyu’ pummelo [Citrus maxima (Burm.) Merr.] and its genetic analysis with simple sequence repeat markers

•This is the first report in which selfed and backed cross progenies of doubled haploid in fruit crops.•Five haploids of ‘Banpeiyu’ pummelo possessed only either one of the ‘Banpeiyu’ pummelo SSR alleles, confirming that they are gynogenetic origin.•Doubled haploid selfing showed fewer production of both developed and undeveloped seeds as compared to ‘Banpeiyu’ pummelo selfing.•Doubled haploid selfed-progenies can maintain exactly the same SSR alleles as their parent.
