 Onion seeds (Allium cepa L.): a selection of varieties

In ICS' working areas, the natural growing conditions are often extreme. Therefore, sowing high quality seeds is essential to lead to profitable crop productions, adapted to local and international markets (fresh, storage and processing onions). In order to provide its customers with suitable seeds, ICS has developed its own registered trade mark: Terradonis®.

Variety choice : a key stage
In tropical areas, variety choice depends more on the destination of the product and the plant's physiological needs than on yield potentials. Storage onions for example must have medium size bulbs, the storage length being reduced when bulbs are too large.

Varietal certification : useful links
Many informations about international product standards for seeds are available on the OECD web site, such as the list of varieties eligible for Certification.
