Seed viability of 61 Avena accessions from the Spanish Crop Genetic Resource Conservation Centre, including valuable endangered landraces, has been evaluated after 10 years of storage. Preservation of seed samples has been conducted under low moisture content (6-7%) and at low temperatures (- 10°C to - 15°C). No differences were detected between the results obtained in the germination assays conducted in 1986 and those obtained in 1996. The maintenance of seed viability during seed storage is due to stable conditions of temperature and, mainly, moisture content; the latter, owing to the air-fight containers used. The determination of the maximum storage periods for each material under local seed storage conditions and integration of compiled information, in the seedbanks, over long periods to time, is encouraged in order to improve the management of Plant Genetic Resource Conservation Centres.
