“FruitBreedomics” European project has been designed by an international consortium including scientists, stakeholders and breeding companies. One of its aims is to increase the efficiency of breeding programs in apple and peach by developing Marker Assisted Breeding (MAB) using novel genomic tools. In the frame of this project, six peach mapping populations (two intraspecific F2, two interspecific F1 derived from P. davidiana, one self pollinated derived from Bolinha and one advanced pseudo-backcross) segregating for mendelian traits and/or Quantitative Trait Loci (QTLs) for pest resistance and fruit quality were genotyped using an Infinium II Illumina bead-chip containing 8144 SNPs derived from the sequencing of the peach genome. Mapping results were contrasted depending on the population considered. Relevancy of using general medium-range SNP bead- chips for breeding purposes is discussed in this study< Réduire
