How registration is done?
How registration is done? Registration is carried out in several steps Step 1: before registration Prior to registration, the status of the samples should be verified to ensure that the following minimum conditions are met before acceptance in the genebank:
The samples should have been acquired from collectors, genebanks or other sources with appropriate material acquisition or transfer agreements and permits in line with national and international regulations regarding conservation, distribution and use.
Samples should be accompanied by adequate passport information especially cultivar name, collector number and pedigree (for genetic stocks and improved material) to ensure that each sample does not already exist in the genebank. The minimum required passport data may include the following:
New samples should be genetically distinct from any other accessions already registered in the genebank. Two samples may have identical or very similar names and identical grain characteristics but may be genetically distinct, while samples with very different names may be genetically similar.
Each sample should be accompanied by a phytosanitary certificate and additional declarations as required under the host country’s phytosanitary regulations.
Seeds or plant materials should be of the highest quality and in adequate numbers for storage.
If the sample does not meet the required conditions, assign a temporary number until the sample is ready to receive a permanent registration number. The temporary number should be easily distinguishable from other accession numbers.
In self-pollinating crops, if a sample comprises of a physical mixture of two or more distinct lines or species, they may be subdivided and maintained as distinct accessions. In this case, subdividing the sample into its components helps in effective maintenance of genetic integrity. Note that subdivision should not be undertaken if variation in the original sample is continuous, as in highly cross-pollinating crops.If samples are registered without adequate passport data, their identities and biological status will remain unknown, hampering their use. Failure to regenerate samples with low viability or very few seeds or plant materials may result in loss of the accession, leaving gaps in inventory. Step 2: Procedure for registration If the sample meets the minimum conditions described above, it may be accepted for registration and assigned an accession number using the following procedure: 1. Arrange the material in alphabetical order by variety name or in numerical order by collection number, depending on the identification provided. 2. Check all packets against the list accompanying the samples. 3. If no list is provided or seeds or plant materials do not correspond to the data, prepare a new list. Check again to confirm that all packets have been included. 4. Check the passport data file to determine the last accession number given. 5. Assign the next ascending accession number to the first sample on the list and consecutive numbers to succeeding samples. 6. Write the accession number clearly on the packet using a permanent marker and on the list of new samples. 7. Enter the details in the passport data files of the genebank’s documentation system. For each accession, record all passport data, original identification data and registration date in the designated fields of the passport data file. 8. If data are missing, leave the field blank and contact the donor to supply the missing data. |

Numbering procedures for new genebanks
A genebank numbering system should be simple and practical to use. 1. Consecutive alpha numeric or numeric codes must be used for each new accession acquired. Assigned numbers are usually preceded by an acronym (such as GBK for Genebank of Kenya) to identify each sample with its registered genebank. Additional information such as year of acquisition and crop code should not be incorporated into an accession number. This code must be linked to all subsequent information about this sample: passport data, designation status and taxonomic information.

Documentation Documenting the information received along with a sample is an important aspect of registration. Information documented at registration consists of passport data providing basic information for identification and general management of individual accessions. |
|
Information systems An information management system must be created in each genebank. This database must be searchable by the genabank curators and staff for specific information through a range of queries. The information system must keep a record of genebank operation data, including storage location, stocks, monitoring, health tests and the distribution status. The same system must also manage germplasm orders, shipment related information and files genebanks ‘contacts’ information. |
