Compiled by Luisa Cagelli Istituto di Sperimentazione per la Pioppicoltura, 15033 Casale Monferrato, Italy   1. Clone name/number Name or number assigned when a clone is entered into the collection. It serves as a unique identifier and is assigned whenever a clone is entered into the collection. Letters should be used before the name/number to identify genebank or national system: ISP_N001 for the material maintained at ISP (Casale Monferrato, Italy) ISP_Brisighella for the material maintained at ISP (Casale Monferrato, Italy) INRA_71002 for the material maintained at INRA (Orléans, France). In this way codes used by the different institutes involved in P. nigra genetic conservation (N001 for ISP Casale Monferrato, 71002 for INRA Orléans, etc.) can be preserved with letters before the clone name/number to identify institutes that maintain a clone. It is important to use letters that identify the institute and not just the country, because in some countries there might be more than one institute involved in genetic conservation. 2. Country where maintained Country in which clone is maintained. International three-letter standard abbreviations (codes) should be used, according to ISO 1988, N. 3166. 3. Institution where maintained Name of institution in which clone is maintained. Abbreviations adopted to identify institutions under "Clone name/number" should be used. 4. Original clone name/number Codes assigned from the institution of origin. This is very important when the clone was obtained from another institution. It could be useful to identify duplicates held in different collections and should always accompany samples wherever they are sent. 5. Collecting number Original number assigned by collector of the sample. This item could be useful to identify duplicates held in different collections and should always accompany samples wherever they are sent (this number may be different from the "Original clone name/number"). 6. Other name/number associated with the clone Any other identification numbers known for this clone. 6.1 Other name/number 1 6.2 Other name/number 2 6.3 Other name/number 3 6.4 Other name/number 4 6.5 Other name/number 5 7. Type of maintenance 0. None 1. Nursery stool-bed 2. Adult plantation 3. Pollen 4. Nursery stool-bed and adult plantation 5. Nursery stool-bed and pollen 6. Adult plantation and pollen 7. Nursery stool-bed, adult plantation and pollen 8. Notes Any additional information should be specified here. 9. Collecting institution Institution which originally collected the sample. 10. Country of origin Country in which the sample was collected. International three-letter standard abbreviations (codes) should be used, according to ISO 1988, N. 3166. 11. Province/State Name of the primary administrative subdivision of the country in which the sample was collected. 12. Department/County Name of the secondary administrative subdivision (within a Province/State) of the country in which the sample was collected. 13. Location of collecting site Name of the nearest town or village where the sample was originally collected. 14. Collecting date of original sample Year in which the sample was originally collected (YYYY). 15. Latitude of collecting site Degrees and minutes followed by N (North) (e.g. Casale Monferrato 45°07' North: 04507N) 16. Longitude of collecting site Degrees and minutes followed by E (East) or W (West) (e.g. Casale Monferrato 8°30' East: 00830E) 17. Elevation of collecting site Altitude above sea level (m). 18. Sex 1. Female 2. Male 19. Female parent When the female parent is known (clone obtained from artificial crossing or from seed collected from known genotypes), the "Original clone name/number" of the female parent should be specified. Include the parents in the database even if they are not currently present in stool-beds (the "Type of maintenance" should then be "none"). 20. Male parent When the male parent is known (clone obtained from artificial crossing), the "Original clone name/number" of the male parent should be specified. Include the parents in the database even if they are not currently present in stool-beds (the "Type of maintenance" should then be "none"). General rules for compilation Material to be included in the database As poplar is propagated by means of cuttings it was decided to include in the database only the clones that are propagated in national collections. Three main types of clones should be included: clones collected in the national territory clones used as parents in controlled crosses: it is important to include the parents of the clones included in the database even if the parents are not currently present in stool-beds (in this case specify "none" in "Type of maintenance"), so as to have some information about the origin of the clones obtained by open-pollination or from artificial crossing clones received from other countries if the original name is known. Type of sample originally collected Although, as already specified, only clones must be included in the database, two different types of samples might have been originally collected: cuttings, if the clone derives from vegetative propagation of a spontaneous tree, or seed if the clone derives from seed collected from a spontaneous tree or from artificial crosses. It is important to make this clear because a lot of the information to be included in the passport database is related to the original sample (collecting number, collecting institution, country of origin, province/state, department/county, location of collecting site, collecting date of original sample, latitude, longitude and elevation of collecting site). Exchange of data It is important to follow some specific rules so that the information from all the EUFORGEN members will be uniform. Characters Only the 26 CAPITAL LETTERS of the English alphabet should be used. This is very important because some particular accented letters existing in some alphabets are not available in computers. File format The information to be included in the database must be forwarded in a file in ASCII format. The size of the fields is indicated in Table 1. If more characters are necessary for some particular fields (e.g. the field "notes" reserved for additional information), they can be enlarged but with specification in the note. If there is more than one word in one field it is necessary to use an underscore (_) between the words (e.g. CASALE_MONFERRATO). Alternatively, the information to be included in the database can be forwarded in a file in EXCEL format. Missing data Dash (-) should be inserted for every missing data: in some cases it will probably be possible to complete the data later (sex, etc.). Empty fields Dash (-) should be inserted also in those fields which are completely empty (such as, probably in many cases "Other name associated to the clone") so as to have the same file structure from every partner. Geographic coordinates The programme Arcinfo for the conversion of geographic coordinates used by different countries can be used. Every participant shall introduce latitude and longitude in the database according to the projection system adopted in the respective country (specifing in a note which system was adopted: e.g. in Italy the system used is UTM). It will be possible to convert the coordinates later if necessary. Table 1. Size of fields (maximum number of characters for each field).
