Chicago Board of Trade (CBOT) grains futures closed lower on Thursday, with once bullish wheat posting losses for the second consecutive day.

The most active corn contract for July delivery fell 6 cents, or 1.63 percent, to 3.6275 U.S. dollars per bushel. September wheat delivery declined by 4.25 cents, or 0.89 percent, to close at 4.7525 dollars per bushel. July soybeans went down 14.75 cents, or 1.61 percent, to 9.04 dollars per bushel.

CBOT floor brokers reported that funds sold 7,000 contracts of corn, 3,000 contracts of wheat and 6,000 contracts of soybeans during the session.

Wheat futures, which had seen a five-day increase, were down on technical selling and a correction of the recent rally, said analysts.

The most recent export report released on Thursday by the U.S. Department of Agriculture showed that soybean sales missed expectations, while corn sales were within but weak, and wheat just beat.

The export data obviously sent a bearish signal to the market, dragging down the prices of corn and soybean futures sharply.

Favorable weather in the corn and soybean growing U.S. Midwest kept additional pressure on their futures, which posted losses for four consecutive sessions.
