3. Records and Archives
-
A website was established, specifically to make the NFC database publically available (www.nationalfruitcollection.org.uk). Prior to this contract, the digital NFC data had been held in a number of different places and formats: key accession details (detailing the origin of the specific accessions in the collection) along with a range of variety specific data from the digitisation of the National Apple Register (Smith, 1971) were held in a Microsoft Access database which was not publically accessible; further details, including general descriptive information about the varieties which the accessions represent, were held alongside the standard photographic images of accessions and flowering time data on the Brogdale Horticultural Trust website (although none of these were searchable); further characterisation data gathered during the verification process were held in a range of spreadsheets (although, whilst data were backed up in hard copy in the archive, some digitised data had been lost at the time of transfer). In addition to this, the working catalogue for the collections was held as a spreadsheet which was updated independently to the Access database. To create a more efficient and co-ordinated system, our approach was to bring all data, as far as possible, into a single web based My-SQL database;
-
As a consequence of the lack of linkage in the original data, a number of inconsistencies were found in the naming or numbering of specific accessions when the files were brought together (individual accession numbers had been allocated retrospectively by the previous curators, based on the records of accession of varieties at Brogdale, but these had occasionally been subject to later change based on new findings around the provenance of the current tree [especially where there had been multiple accessions for a given variety]). These inconsistencies were addressed through bringing the Access database together with the spreadsheet based catalogue and data (Milestone 2), allowing the NFC database to differentiate where data belonged to the current, rather than a previous accession, and to correctly align with the situation in the field, in cases where accessions had been deaccessed, lost and/or re-accessed under a new number. The database was made publically available from an early stage (Milestones 4 and 8);
-
Fewer digitised data sets were available than was expected at the start of the project and additional data were consequently digitised for inclusion in the database; these included descriptive data generated during verification of the Cherry and Pear collections. Additionally, raw data used to generate 10-year flowering time means were digitised as it was apparent that these contained further, useful details for understanding the seasonal, and climatic variations in flowering time. Further data collected through the ongoing verification process and through monitoring of flowering time were also added to the database;
-
Pre-existing characterisation data for the apple collection were standardised where possible to align with the ECPGR standardised descriptors (IBPGR/CEC 1982, and currently in updated draft form). Whilst the ECPGR descriptors themselves had been used as a basis for the verification process, the data recorded often quoted multiple, or concatenated descriptors in an attempt to include the variation within the biological sample (and to allow for the subjectivity of the descriptors). Many of the other data included in the verification records were taken directly from the National Apple Register (Smith 1971) as this had been accepted as a record of the historical verification of the accessions in cases where the material was held at Brogdale at the time of writing. However, the National Apple Register contains descriptions both from Brogdale (although made before the ECPGR recommendations) and from the published literature, and the consequence of this was that these descriptions included a much wider set of descriptors than the ECPGR standards, or than were suitable for use in a workable search tool (for example, 141 ‘unique’ descriptors were included for ground colour [including ‘whitish green’, ‘pale green’, ‘pale greenish white’, ‘whitish green/green’ and ‘whitish/green’ amongst others] where the updated draft ECPGR set allows for Yellow, Whitish yellow, Green yellow, Whitish green, Green, Orange, or Red. Similarly, 405 ‘unique’ descriptors had been used for shape). Having standardised these data, new search protocols were able to be developed (Milestone 25) to make the data considerably more accessible to users (Milestone 10); to clarify the original source, the data were also individually referenced to either the NFC archives or the National Apple Register in the database;
-
Numerous images of fruit on the tree and blossom had been taken during the previous contract but had not been processed for inclusion in the database. Over 6,000 images of fruit or blossom were screened to select approximately 1,800 for inclusion in the database; a further 333 images of cherry and plum fruit were also identified for inclusion. Additional studio images were taken in a standard format and/or processed for inclusion and 468 further studio images were added to the database. A further 323 images of fruit on the tree were taken in the apple and pear collections for inclusion. A summary of the current status of the image collection in the database is included in 3.2;
-
A name checking tool was developed within the database. This was produced initially in line with the aims of ECPGR, where it has been identified that many collections hold matching accessions under different local names, some of which will be recognised within the National Apple Register list of synonyms and some of which will not. The tool is able to check a given list of accession names against approximately 23K names in the database and either identify uniquely recognised names/synonyms, or highlight homonyms (where names have historically been used for more than one variety, as either an accepted name or synonymously), or alternatively, to allow the user to propose and align their new synonyms or local names with existing accepted names. This tool was used in the alignment of the other UK collections (described further below) to the NFC data and was demonstrated and utilised at the ECPGR Malus/Pyrus meeting in Weggis (2012);
-
Other additions to the database included creating links between related accessions based on shared parentage, so that users can access details of offspring or parental varieties in the collection, as well as clonal information, to link accessions with their clones or sports. Accessions were also linked based on shared periods of flowering. Accession and deaccession notices have been added to the website to highlight new or outgoing material (Milestone 27).
-
Full lists of accessions were supplied and included in the UK National Plant Inventory on a regular basis (with kind help from colleagues at the University of Aberystwyth) and these were subsequently used to update the EURISCO database. Full accession lists and descriptive data were also supplied to the Fera Plant Varieties and Seeds team in line with the need to develop a UK national list of fruit varieties. Data were also supplied to Plant Heritage to aid with their assessment of the status of cultivated varieties as part of their Threatened Plants Project. Full listings of names were supplied to the RHS for use by their taxonomy team and both accession names and descriptive data were made available and utilised in the EU FruitBreedomics project. In addition, various smaller sets of data and information were supplied on a regular basis in response to requests from researchers, nurserymen, horticultural groups and the public (although these were too numerous to detail);
-
Collection listings were processed for a number of other significant UK collections with a view to their inclusion in the NFC database. The aim of this was to develop the NFC database as a more inclusive database for the fruit tree genetic resources held in collections within the UK, to allow us to recognise where material from additional varieties was held, as well as monitoring where accessions in the NFC may effectively be backed up in other collections. Initially, this was started with the inclusion of listings from the Plant Heritage National Plant Collection™ of Perry Pears at Hartpury.
-
The hard copy paper archives and library at Brogdale were in need of assessment at the start of the project. The archive/library contained a combination of materials, many of which had been left over from the time when Brogdale was an experimental horticulture station (Brogdale EHS). During transfer from the previous contract, carried out by the Brogdale Horticultural Trust, there had been a lack of clarity on which material should be strictly the responsibility of the NFC and a process of rationalisation of the library was therefore carried out. A number of long unbound runs of trade magazines and journals, of little direct relevance to NFC, along with extensively replicated reports and leaflets (accrued in the time of Brogdale EHS) were disposed of with a view to focussing the archive on material which was of relevance to the current collections and had potential value as a resource at Brogdale.
Further details relating to the above are summarised below (with additional detail included in annual reports):
