Paeonia ostii x Paeonia suffruticosa Raw sequence reads. Paeonia ostii x Paeonia suffruticosa

The main aim of this study was to discover large-scale genome-wide molecular markers and construct a high-density linkage map in tree peony. We selected an optimizing segregation population, derived from the cross P. ostti ‘FenDanBai’ × P. × suffruticosa ‘HongQiao’, for genetic linkage mapping. We exploited specific-locus amplified fragment sequencing approach to identify large-scale molecular markers and generate genotype data from this segregation population. Subsequently, using these data, we constructed the first high-density linkage map for tree peony.
