French seed production fell across all species after repeated heatwaves and drought in summer 2026, according to the UFS seed industry union. Maize seed targets are only 65-70% met, and sunflower reaches 80-85% of targets, though the union says variety availability is assured.
Lower seed output tightens planting supply for spring crops and may reduce EU maize and sunflower acreage potential, a modest support for feed grain and sunflower meal prices.
