Simple sequence repeat (SSR) microsatellite markers have been extensively used to identify duplication and analyse genetic diversity in germplasm collections of apple. Here, we present findings from the use of a standard set of SSR loci in the managed repropagation of a significant international germplasm collection: the UK National Fruit Collection (NFC). A subset of eight SSR loci was deemed sufficient to distinguish all apart from the clonal accessions across a sample of 1,995 accessions, with a single exception being a pair of full siblings. In total, 99% of accessions were able to be confirmed to be present and correct after the replacement of trees initially identified to be incorrectly propagated. In parallel to the curation of the collection itself, through an initiative led by the UK local apple enthusiast community, 3,373 SSR profiles for apples held in local collections were compared to the NFC holdings. Overall, in both sets of material, diversity remained high with average gene diversity values of 0.800 and 0.812 in the NFC holdings and local collections, respectively. Accessions in local collections were not found to differ in their overall coverage of genetic diversity to that of the NFC collection (FST = 0.0035) although significant numbers of locally valued, and genetically distinguishable individuals were identified, some of which may represent ‘lost’ cultivars.
