MULTI-CROP PASSPORT DESCRIPTORS

  1. 1. Multi-Crop Passport Description – EU Project GrapeGen06 MULTI-CROP PASSPORT DESCRIPTORS (MCPD) for Grapevine to be used for the European Project Index Document 1. FAO/Bioversity Multi-Crop Passport Descriptors - -General all species Document 2. Multi-Crop Passport Descriptors - Specific for Grapevine Document 3. Palic Meeting (APPENDIX II): Passport data and descriptor recording rules to be applied for the European Vitis Database (www.eu-vitis.de) Document 4. Excel file format, for uploading MCPD data into the European Vitis Database and the exchange of MCPD data among partners, is downloadable from the cited website. 1
  2. 2. Multi-Crop Passport Description – EU Project GrapeGen06 Document n. 1 FAO/Bioversity MULTI-CROP PASSPORT DESCRIPTORS December 2001 The list of multi-crop passport descriptors (MCPD) is developed jointly by Bioversity and FAO to provide international standards to facilitate germplasm passport information exchange. These descriptors aim to be compatible with Bioversity crop descriptor lists and with the descriptors used for the FAO World Information and Early Warning System (WIEWS) on plant genetic resources (PGR). For each multi-crop passport descriptor, a brief explanation of content, coding scheme and suggested fieldname (in parentheses) is provided to assist in the computerized exchange of this type of data. It is recognized that networks or groups of users may want to further expand this MCPD List to meet their specific needs. As long as these additions allow for an easy conversion to the format proposed in the multi-crop passport descriptors, basic passport data can be exchanged worldwide in a consistent manner. General comments: • If a field allows multiple values, these values should be separated by a semicolon (;) without space(s), (i.e. Accession name:Rheinische Vorgebirgstrauben;Emma;Avlon). • A field for which no value is available should be left empty (i.e. Elevation). If data are exchanged in ASCII format for a field with a missing numeric value, it should be left empty. If data are exchanged in a database format, missing numeric values should be represented by generic NULL values. • Dates are recorded as YYYYMMDD. If the month and/or day are missing this should be indicated with hyphens. Leading zeros are required (i.e. 197506--, or 1975----). • Latitude and longitude are recorded in an alphanumeric format. If the minutes or seconds are missing, this should be indicated with hyphens. Leading zeros are required. • Country names: Three letter ISO codes are used for countries. The ISO 3166-1: Code List and the Country or the Country or area numerical codes added or changed are not available on-line, but can be obtained from Bioversity [ipgri-mcpd@cgiar.org] • For institutes the codes from FAO should be used. These codes are available from http://apps3.fao.org/wiews/ for registered WIEWS users. From the Main Menu select: ‘PGR’ and ‘Download’. If new Institute Codes are required, they can be generated online by national WIEWS administrators, or by the FAO WIEWS administrator [Stefano.Diulgheroff@fao.org]. • The preferred language for free text fields is English (i.e. Location of collecting site and Remarks). 2
  3. 3. Multi-Crop Passport Description – EU Project GrapeGen06 MULTI-CROP PASSPORT DESCRIPTORS 1. Institute code (INSTCODE) FAO Institute Code of the institute where the accession is maintained.

  14. 14. Multi-Crop Passport Description – EU Project GrapeGen06 Document n. 3 Palic Meeting – Discussion and Recommendations APPENDIX II Passport data and descriptor recording rules for the compilation of the European Vitis Database General remark: any field without information should be left blank. The provided format file should be strictly adhered to. 1. Passport data a. The adopted model is the complete list of the “FAO/IPGRI Multi Crop passport data”, extended with the EURISCO descriptors (see Appendix I), consisting of 33 descriptors. b. Within those 33 descriptors, the following should be given priority: Species, Accession number, Accession name, Institute code, Donor institute code, Common crop name (i.e. Table grape, Wine grape, Raisin grape, etc.), Ancestral data and Acquisition date. c. Four additional passport descriptors for Vitis are: i) berry color with the recommended notations: B (white), N (black), Rs (rose), G (grey) and Rg (red) ii) The variety name, after identification iii) country of origin ot the variety: code of the country in which the variety originated and iv) year of crossing: year in which the variety was created. (The last two descriptors have been added after the Palic meeting.) 2. Primary descriptors (ampelographic) a. Notations consist of numbers from 1 to 9 b. More than one notation can be adopted for one single descriptor if: i. Two or more expression levels occur during the observation (phenotype variability) ii. The appropriate notation is between the two closest expressions levels. In the previous cases, use the two or more notations separated by | without spaces (examples: 5|7 or 3|7|9) c. For qualitative descriptors the expression levels can occasionally be discontinuous (examples: 1|5|7 or 1|2|4) 3. Primary descriptors (ampelometric): a. Do not use expression levels (1, 3, 5, 7, 9) but measured parameters b. One single notation is recommended (average) c. Values in mm for lengths and in degrees for angles (no decimals) 14
  15. 15. Multi-Crop Passport Description – EU Project GrapeGen06 4. Secondary descriptors a. Give proper attention to measurement units and decimals indicated in descriptor definitions 5. Molecular markers a. Data must be coded following the rules specified in the descriptor definitions (example: N+14) b. The first data recorded has to be the smaller allele. In case of homozygosis, use the same value for the second recorded data. In case a third allele occurs, record a third data. c. Rough data (non codified) can be given referring to the 2 or 3 alleles. d. Publication references can be provided. 15
