The International Seed Testing Association was founded in 1924 during the 4th International Seed Testing Congress held in Cambridge, UK, with the aim to develop and publish standard procedures in the field of seed testing.
ISTA membership consists of Member Laboratories and Sampling Entities, Personal Members and Associate Members, from 83 countries/distinct economies. More than 130 of the Member Laboratories are accredited by ISTA and entitled to issue ISTA Certificates. The membership is a diverse collaboration of seed scientists and analysts from universities, research centres and seed testing laboratories around the world.
ISTA acts free from economic interest and political influence, and is unbiased, objective and fair. Our expertise is based on non-profit cooperation from an international community of over 400 competent and energetic seed scientists and analysts. ISTA works in developing standard seed testing methods, facilitates the trade of quality seeds and makes a valuable contribution to food security.
