The advent of next-generation DNA sequencing(NGS)technologies has led to the development of rapid genome-wide Single Nucleotide Polymorphism(SNP)detection.Genotyping by sequencing(GBS)where sequences are used simultaneously to detect and score SNPs,is one of approaches based on NGS and bypassing the entire marker assay development stage and thus it combine molecular marker discovery and genotyping.Here we applied GBS approaches for SNP discovery in apricot.
