Wheat was up 2 to 8 cents per bushel, with September up 5 at $7.88-1/4 per bushel. Market technically oversold and due for a recovery bounce. Gains limited by big global wheat production this year and declines in corn and soya. USDA said export sales of US wheat last week totalled 610,400 tonnes (old-crop), within estimates for 500,000 to 700,000 tonnes.
