CHICAGO, Sept 24 (Reuters) - Chicago Board of Trade corn futures retreated on Wednesday on rising supplies from an accelerating U.S. harvest and spillover pressure from sinking soybeans.
Losses were limited by concerns that U.S. corn yields would not be as large as the government and some private forecasters expected.
The U.S. Department of Agriculture is forecasting the largest-ever U.S. harvest this fall with record-large yields. But scattered reports from early-harvested fields suggest that yields in some areas were hurt by dry late-summer weather and pockets of plant disease.
The USDA is due to release weekly export sales data early on Thursday. Analysts surveyed by Reuters expect net U.S. corn export sales in the week ended September 18 at 1.0 million to 1.8 million metric tons.
CBOT December corn CZ25 settled 2 cents lower at $4.24-1/4 per bushel.
