Abstract
The present system of formal plant germplasm conservation in Canada began in 1970 with the appointment of the first Plant Gene Resources Officer. Agriculture and Agri-Food Canada (AAFC), which has the main mandate for plant germplasm conservation, operates a seed genebank in Ottawa, which stores and documents accessions of value to Canada, and a clonal genebank in Smithfield, which concentrates on the preservation of tree and small fruits. A new multi-nodal system initiated under the Green Plan has added five new centres to the plant germplasm network. Located at AAFC research centres, plant breeders are responsible for rejuvenating and documenting important germplasm. Universities, companies and nongovernmental organizations contribute to germplasm conservation by increasing the genetic diversity available in the form of cultivars and operating plant and seed repositories. Key words: Germplasm conservation, genebank
