Abstract: For the development of a large number of SNP for the construction of high quality genetic map of cultivated strawberry(Fragaria×ananassa,2n=8X=56),Hongxing×Benihoppe crossing populations were sequenced by SLAF-seq that yielded 565 919 066 reads, with Q30 value of 95.36% and GC content of 39.68%. 717 881 SLAFs and 2 136 939 SNPs were identified.Total 56 237 SNPs showed high quality for genetic map construction, of which 14 412 were successfully mapped to 28 linkage groups spanning a total of 4 022.16 cM with an average interval genetic distance of 0.28 cM. It was showed that the greater part of each individual was derived from the parents by evaluating the monomer source of the genetic map. The results of heat map showed that the sequence of most markers on each linkage group was consistent with the genome, the sequence of markers was correct, which could show that the map was of high quality.A high-density genetic map of cultivated strawberry by SLAF-seq could be laying a foundation for genetic research and molecular marker-assisted breeding of cultivated strawberry.

Key words: Cultivated strawberry, SLAF-seq, SNP, High density genetic map
