Structural and Functional Apple Genomics and its Application in Breeding

The present paper summarized some knowledge of modern technologies, applied in apple (Malus domestica) genome studies. New generation sequencing allowed single nucleotide polymorphism (SNP) chip technologies for genotyping, description of functional apple genes, characterization of the evolutionary results in apple genome fragment transition, as well as phylogenetic reconstruction of the genus Malus, being the confirmed progeny of M. sieviersii. Based on these technologies, newly developed putative markers may give the most important biological data such as age, geographical origins, tissue type determination, and external visible characters. The new generation genotyping platforms, representing very high efficiency, are now successfully applied for random apple genome-wide association (GWA) studies as well pedigree-based analysis and marker-assisted selection (MAS).
