6. CONCLUSIONS
• Peach genome is structured in big blocks of variability
• In general, each breeding program has its own pattern of
variability (breeder+ “founders”+ breeding location
imprint)
• A deep view of genome-wide variability can be used to:
• localize genes
• direct the variability for crosses
• manage the variability in a germplasm collection
