Since its publication in 2013, the high quality genomic sequence of peach (Peach v1.0), with about 28,000 genes annotated, is being used as a basic tool for different purposes: from the study of genetic diversity within the whole genus Prunus, to the characterization and isolation of genes involved in key processes related to relevant agronomic traits, and for the application of Marker Assisted Breeding (MAB). The resequencing of a panel of eastern and western cultivated peach varieties and wild species has led to the identification of about 1 million molecular markers (SNPs) and has shown a lower level of variability within the cultivated peaches compared to the wild relatives. The Peach v1.0 assembly is being used worldwide in candidate gene approaches for the identification of genes involved in monogenic and polygenic (QTL) traits, not only in peach, but also in other stone fruit species. Another valuable resource coming from the peach genomic sequence is the IPSC 9k array , containing about 9,000 SNP markers in peach and the 6,000 SNP markers array in cherry, which can be screened at one time in genome-wide approaches. The final goal of all these approaches is to identify the best genotype/genes (haplotypes) combinations for a given phenotype.
