Verifying accompanying documentation

The following is a list of required documentation to be sent with the new materials.

Verifying the consignment

The following is the required inspection procedure for plants to determine any plant health problems.

Assigning numbers

New accessions are usually received as small samples of in vitro cultures, classical vegetative propagation material (young suckers) or as seeds.

If the conditions described above cannot be met, then a temporary accession number must be assigned and plantlets must go through the necessary disease cleaning or multiplication process until they can be assigned a permanent number.

Procedures for disease testing

Procedures for disease testing at ITC include sending a set of five cultures to Virus Indexing Centres at CIRAD, France, QDPI, Australia or PPRI, South Africa, where the materials are tested for the presence of the five major banana viruses:

Extra samples

A separate subset of material can be kept after registration, to be regenerated under greenhouse conditions, for harvesting leaf samples that can be processed for DNA/lyophilized leaf bank. These banked leaf materials can serve as a reference for molecular identification for the germplasm stored in the active and base collections and samples can be made available to users for research in gene discovery and function, marker development and detailed genotypic characterization.

Recording information during registration

New materials – Introduction phase

Newly introduced meristems or nodal cuttings should be processed in batches. For each batch, a series of information should be recorded in a table with the following fields (at IITA):

Musa Germplasm Information Systems (MGIS)

In 1997, INIBAP laid the basis for a global information system for Musa through the release of MGIS. The aim of the system was to enhance knowledge on Musa diversity, to help rationalize conservation and to improve the use of banana genetic resources though a facilitated access to comprehensive information.

In 2005, the MGIS database contained key information, including passport data, botanical classification, morpho-taxonomic descriptors and characteristics such as agronomic traits, disease resistance, stress tolerance, biochemical or molecular genetic markers, and plant photographs, as well as GIS information on 5188 accessions managed in 18 banana collections around the world, making it the most extensive source of information on banana genetic resources.

The database is publicly accessible through the internet here. This global database can be queried on the identity, origin, characteristics and distribution of the individual accessions in the collections. This allows curators of the participant institutions worldwide to share and compare their data. The database is also particularly helpful for various germplasm users, namely breeders, researchers and farmer communities, to locate alternative sources of banana germplasm and identify the most appropriate accessions with particular traits of interest.

The Genebanks

The 11 CGIAR genebanks currently conserve 730,000 of cereals and grain legumes, forage crops, tree species, root and tuber crops, bananas and crop wild relatives.
