OUR GOAL: Collect, conserve and distribute the world’s vegetable germplasm, identify genes for valuable traits, and incorporate these into improved lines using classical breeding and molecular techniques
The AVRDC Genebank maintains the world’s largest public vegetable germplasm collection with more than 61,000 accessions from 155 countries, including about 12,000 accessions of indigenous vegetables. Collecting and conservation work is done in collaboration with national partners who maintain duplicate collections.
Molecular characterization and genetic diversity analysis of selected germplasm collections is done to identify markers and map genes linked to important agronomic traits such as disease resistance, stress tolerance, or high nutritional value. This significantly enhances the efficiency of breeding programs as key genes can be identified for introgression into improved lines.
What Genebank staff do
- Conserve and distribute vegetable germplasm to improve crops
- Identify superior sources of genes for important horticultural traits
- Characterize the Center’s germplasm to make better use of its diversity
- Develop DNA markers for improved traits for marker-assisted selection
- Use molecular technologies to isolate and validate genes affecting important traits
- Share the benefits of the Center’s germplasm collections
- Train partners in germplasm conservation, use, and gene discovery
Since its founding, the Center has distributed more than 600,000 seed samples to researchers in the public and private sectors in at least 180 countries. This has led to the release of hundreds of varieties throughout the world, especially in developing countries.
The AVRDC Genebank is part of Genesys — the global information and germplasm exchange network.
The AVRDC Vegetable Genetic Resources Information System (AVGRIS) contains data on all the accessions held by the Center. AVGRIS is used by our staff to manage the collection, and by our partners to assess and order materials for their breeding programs. The Center uses standard Material Transfer Agreements (MTAs) for sharing genetic material and provides training to partners in the conservation and evaluation of vegetable genetic resources.
