Pollen transport from genetically engineered corn was evaluated by testing corn offspring from nearby cornfields. Harvested corn, sown in greenhouse flats, was sprayed with glyphosate at second leaf stage. Corn resistant to glyphosate likely cross-pollinated with GE corn or came from contaminated seed. Overall cross-pollination was less than two percent.

Key words: Glyphosate-resistant corn; genetically engineered corn; corn pollen; pollen transport; corn seed purity; transgene.
