Genotyping-by-sequencing of Canada's Apple Biodiversity Collection

Canada's Apple Biodiversity Collection (ABC) is one of the most diverse collections of apples in the world, which was designed to enable genetic mapping. The ABC is located at the Agriculture and Agri-Food Canada (AAFC) Kentville Research and Development Centre in Nova Scotia, Canada. In addition to phenotypic descriptions of the ABC, sequencing the accessions in the collection provides a valuable resource not only for researchers working on the collection, but for those studying apples more broadly. With this in mind, we report and make publicly available genotyping-by-sequencing (GBS) data for over 1,000 apple accessions from the ABC. By using three SNP callers and imputation, we were able to genotype 278,231 SNPs from 1,175 diverse apple accessions from the ABC.
