December wheat opened 8 1/2 cents lower on the day at 802 1/2 and established an early range of 801 to 814 1/4. Traders said that the lower open came in line with lower trade in wheat overnight as well as the International Grains Council's latest estimate of world wheat production. The IGC raised its estimate by 10 million tonnes to 672 million tonnes, a new record. This is the latest in a series of USDA and IGC estimates that have moved the world wheat crop to a succession of news record highs. Wheat rallied to slightly higher on the day into early mid session, although it continued to lag corn. Australia's eastern wheat-producing state of New South Wales is still expected to see rains over the next three days, but amounts in the drier northern areas of that state may only be 1/2 inch. Ukraine's ministry of agriculture said today that 96% of this year's wheat crop is on track to reach 26.8 million tonnes, about in line with previous estimates. The Chicago Board of Trade corrected this morning's deliveries against the September contract. Actual deliveries in wheat were just 3,561 contracts compared to a previously released total of 4,032 contracts.
