The development of the GSCC will be based on a thorough assessment of the cacao genetic diversity currently conserved in ex situ collections and the identification of those unique accessions for use by breeders and researchers, available in the international and national collections. It will be a dynamic and geographically dispersed collection composed mainly of wild accessions and landraces. The backbone will consist of accessions from the international collections managed by CATIE and CRU/UWI collections, for which considerable characterization and evaluation data are already available in the public domain, complemented with priority accessions from national collections.
The GSCC has criteria that will be used to identify priority accessions. A first set of accessions will be selected on the basis of capturing the greatest possible genetic diversity (in the form of allelic richness) held in ex situ collections worldwide. A further set of accessions will be selected on the basis of key traits of interest to breeders and farmers, such as yield, flavour characteristics and disease resistance. The allelic richness component of the GSCC will be relatively static, with new accessions introduced as they are made available from national collections or if unique material is found during collecting missions.
Global system for the conservation and utilization of cacao genetic resources
The trait component of the GSCC, however, will be more dynamic and subject to a process of rationalization, where existing accessions may give way to new material that expresses a given trait more highly or has a better combination of traits.
Partners will agree on how to share responsibilities for conserving and distributing material from the GSCC, and long-term funding will be discussed with the Global Crop Diversity Trust, other international donors and with the private sector. CacaoNet expects to continue to facilitate the dialogue between the ITPGRFA and the countries that are maintaining cacao materials targeted by the GSCC, in order to encourage countries to follow the example of CATIE and CRU/UWI and place selected accessions under the Treaty. CacaoNet will also ensure the continuing development of the GSCC in consultation with all its members.
Geographic Information Systems (GIS) will be used to map the spatial distribution of different cacao populations, using additional information about genetic diversity in wild cacao populations to guide future collecting missions. In addition, collecting will be directed to places where one might reasonably expect to find a higher frequency of desirable traits, such as disease resistance. The main priority for collecting will be to fill gaps in ex situ collections, with a focus on threatened wild relatives of cacao and landraces.
The research will be carried out by a network of experts with complementary skills in taxonomy, diversity analysis and conservation of genetic resources, especially in situ conservation. CacaoNet will play a role in ensuring the participation of key stakeholders and to build capacity in diversity analysis in the partners responsible for conservation of cacao in its centre of diversity.
The Global Strategy calls for a greater effort to understand and conserve the diversity of cacao and its wild relatives, using a variety of initiatives such as national forest reserves, wildlife refuges, and private reserves, all of which can help preserve natural plant communities. Partnerships with governmental agencies with responsibility for forestry and environmental issues and local-level authorities in target countries, plus national and international conservation NGOs, forestry research institutes, farmer communities and civil society organizations, as well as the private sector, will be needed for successful in situ and on-farm conservation.
CacaoNet will work with the International Plant Protection Convention (IPPC) and its regional organizations to ensure that the updated guidelines are widely available to those responsible for the phytosanitary systems in cocoa-producing countries. Part of this will involve developing effective ways to raise awareness of the importance of safe movement of germplasm to the cacao community, working closely with groupings such as INGENIC and COPAL.
The Global Strategy will strengthen the current system of germplasm distribution through the ICQC,R and support the development of new quarantine centres in each of the three regions (Americas, Africa and Asia) to facilitate the safe intraregional movement of germplasm.
To facilitate the selection of new accessions to be introduced by user countries, a list of the main traits of accessions held in the ICQC,R will be compiled, which will help breeders identify materials of potential interest that are currently available for international distribution. Moreover, information in the ICGD and CANGIS will assist them in prioritizing material from local and international genebanks for inclusion in their breeding trials following appropriate quarantine procedures. This work will be done in collaboration with INGENIC and the regional breeding networks where CacaoNet will play a coordination role.
The identification of the most useful GSCC germplasm for distribution, adapting to the evolving needs of breeding programmes, will continue. Germplasm of current interest includes the material from the CFC/ICCO/Bioversity project, materials from the black pod and witches’ broom enhancement programmes in CRU/UWI and genotypes with frosty pod resistance identified in CATIE.
As part of the GSCC information portal, a central database, CANGIS (CacaoNet Germplasm Information System), will bring together all the genebanks and other service providers that collectively form the GSCC and facilitate their effective management. CANGIS will maintain specific, high quality data (including passport descriptors and the characters supporting an accession’s inclusion in the GSCC) on all the individual accessions (trees located at specific sites) that make up the GSCC, and provide a means for users to access this germplasm. CANGIS will coordinate the compilation of characterization and evaluation data from all collections, supported by the molecular verification of the accessions to which the data pertain. CANGIS will link to existing international databases, such as ICGD and TropGENE, in order to access additional information that is of interest to potential users of the germplasm.
Mechanisms will be developed to link the GSCC to information and local knowledge on in situ and on-farm genetic resources. These databases will be linked over time to multicrop global information systems, such as GENESYS, as they are developed.
Components of the GSCC Information Portal
1: Characterisation and evaluation data are sent to ICGD (includes non-CacaoNet accessions and information).
National cocoa research institutes and their governments will play a key role in ensuring access to a wide range of diverse genetic resources and related information, facilitating the rationalization of collections and building trust among partners. There will have to be dialogue with decision-making political and administrative bodies in each country, not least to facilitate implementation of agreed regulations for cacao quarantine. Capacity building will need to provide training and equipment support to the collections in the GSCC, with particular reference to genebank management, germplasm evaluation, information management and data analysis, and policy and legal aspects of germplasm exchange.
CacaoNet will play an important part in these efforts. It will ensure agreement on the establishment of the GSCC and oversee its development on behalf of all its members, and will actively engage in fund-raising for the implementation of the Global Strategy. CacaoNet will also encourage collaboration with national collections, FAO and the ITPGRFA to help ensure that germplasm, particularly accessions identified for inclusion in the GSCC, is placed in the public domain.
