France’s seed producers reported an exceptionally poor 2026 campaign after summer heat damaged seed crops, especially maize. The French seed association estimates maize seed output at 65–70% of its initial target, with quality problems potentially reducing marketable volumes further; the overall French market is expected to be supplied, but shortages of some early varieties and lower exports are anticipated.
Reduced seed availability could constrain farmers’ planting choices and increase competition for early-maturing maize varieties ahead of the 2027 crop. Lower French seed exports may also tighten supply for importing markets, though the domestic market is expected to remain broadly covered.
