The seed activity of the Maïsadour Cooperative Group began in 1949, a few years after the creation of the farmers cooperative, in 1936, in the South-West of France. The ambition was then very strong: to produce, create and supply quality hybrid maize seeds in a growing French market. This ambition has been largely exceeded 70 years later.

Today, MAS Seeds has become an international seed company, commercially present in more than 50 countries, with more than 60% of its workforce spread out of France. Recognized in maize but also in sunflower and alfalfa, it also intervenes in other plant species. To reflect the new ambitions of the company, the brand needed a new name and an updated image fitting into its history and better adapted to the international dimension and the diversity of its activities. Thus, in 2018, Maïsadour Semences became MAS Seeds.
