Instituto Nacional de Investigaciones Agropecuarias (INIAP, Ecuador) began the collection and conservation of germplasm in 1980. DENAREF (National Department of Plant Genetic Resources) is the technical service and research unit of INIAP that has significantly contributed to ex-situ and in-situ conservation activities to make germplasm available to different users such as farmers, breeders, agro-industrialists and scientists.
DENAREF maintains about 28,000 accessions at INIAP Santa Catalina research station (Headquarters) and other experimental stations throughout Ecuador. Passport data for maize, beans, potato, sweetpotato, and cassava is available in Genesys.
