High-density genetic map of Schima superba constructed by GBS

A high-density genetic map was constructed using genotyping by sequencing (GBS). An F1 full-sib with 116 individuals and their parents (LC31×JO32) were sequenced on the Illumina HiSeqTM platform. Overall, 343.3 Gb of raw data containing 1,191,933,474 paired-end reads were generated. Based on this, 99,966 polymorphic SNP markers were developed from the parents, and 2209 markers were mapped onto the integrated genetic linkage map after data filtering and SNP genotyping. The map spanned 2076.24 cM and was distributed among 18 linkage groups. The average marker interval was 0.94 cM.
