Abstract

This dataset comprises over 12,000 high-resolution images of apples collected from Canada’s Apple Biodiversity Collection, housed at Agriculture and Agri-Food Canada’s Kentville Research and Development Centre. Each apple was photographed from both the top and side views, capturing more than 500 genetically unique accessions. For each image, three versions are included: the original, a colour-corrected version, and a binary (segmented) version to support various analytical applications.

Using a pseudo-landmarking approach, we determined that the primary source of morphological variation among the apples is related to shape rather than size. To support reproducibility and further analysis, the dataset also includes an initial metadata file that serves as a foundation for conducting morphological assessments.
