CHICAGO, Feb. 14 (Xinhua) -- Chicago Board of Trade (CBOT) futures were trading mixed on Wednesday morning with wheat retreating over profit-taking.

As of 1542 GMT, March corn was up 0.75 cent at 3.675 U.S. dollars per bushel while March wheat was down 4.5 cents at 4.5625 dollars and March soybeans up 1.25 cents at 10.13 dollars per bushel.

CBOT wheat futures saw more than three percent rally earlier this week and now are sinking in corrective trade.

Profit-taking and more favorable weather in the eastern U.S. plains, dragged down wheat prices, said market observers.

Soybeans were lower in overnight trading as prices continue their see-saw action, but started to post moderate gains in the morning session.
