Vylor, set to become independent from Corteva on 1 October 2026, and Belgian agricultural biotech startup Rainbow Crops have entered a collaboration to develop gene-edited corn traits using AI, multiplex genome editing, precision breeding, and automated phenotyping, targeting improved resilience to heat, drought, and flooding.
U.S. grain futures on September 25, 2026 finished near session highs after early selling pressure gave way to a recovery driven by a weaker dollar and trade-deal optimism.

Persistent Midwest rains are delaying harvest and tightening soybean supplies at processors.
Grain futures moved higher overnight on September 16, 2026, led by a surging soybean meal market that reached a 2.5-year high.
