September wheat was up 34 cents at $7.99-3/4 per bushel, December was up 33-1/2 at $8.24-1/4. Technical bounce after fund-driven sell-off on Wednesday; strong weekly export sales add support. USDA said 682,600 tonnes of US wheat (all 2008/09) sold for export last week, above trade estimates for 450,000 to 650,000 tonnes.
