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.
