SNP genotyping Dutch heritage apple cultivars allows for germplasm characterization, curation, and pedigree reconstruction using genotypic data from multiple collection sites across the world

The curation and preservation of Dutch apple germplasm depends on reliable accession level information. However, many accessions of Dutch heirloom apple cultivars maintained publicly by the “Centre for Genetic Resources, the Netherlands” (CGN) and privately by Dutch pomological societies lack information regarding true-to-typeness and pedigree ancestry. The aim of this study was to address this knowledge gap by genotyping 652 apple accessions maintained in the CGN collection and Dutch private collections, compare their genotypic information to each other and to a large database of apple cultiv...
