U.S. wheat rose for the first time in six sessions on Thursday, rebounding from 5-1/2-year lows hit on Wednesday, on bargain-buying, signs of more global import demand and expectations of reduced U.S. sowings.

Chicago Board of Trade front-month wheat rose 0.9 percent to $4.46-3/4 a bushel at 1040 GMT. The contract had touched its lowest since June 2010 at $4.38 a bushel on Wednesday, pressured by abundant global supplies and weak demand for U.S. wheat.

Front-month soybeans rose 0.1 percent to $8.69 a bushel and front month corn rose 0.2 percent to $3.60-3/4 a bushel. Both were pressured on Wednesday by prospects of large South American crops.

"Wheat is being supported by bargain-buying after the sharp falls yesterday, by expectations of a smaller U.S. sowed area and signs of more demand in the market with some large tenders seen today," said Frank Rijkers, agrifood economist at ABN AMRO Bank. "But prospects of ample global wheat supplies are still hanging over the market, retaining bearish sentiment overall."

"Soybeans and corn are also being supported by bargain buying after their falls and are also seeing some spillover support from wheat."

The U.S. Department of Agriculture (USDA) will release U.S. acreage forecasts at its two-day Outlook Forum on Thursday and Friday and is expected to predict U.S. farmers will increase corn and soybeans sowings this year.

"If farmers plant more corn and soybeans this means they are likely to plant less wheat which is supportive for wheat today," Rijkers said. "The low prices also seem to be generating some more demand, with large new import tenders issued by Saudi Arabia, Egypt and Taiwan."

Saudi Arabia issued a large buying tender for 770,000 tonnes of wheat on Thursday after not having made a purchase since October 2015. Egypt also issued a tender for an unspecified volume.

Taiwan tendered to buy 100,975 tonnes of wheat to be sourced from the United States.

"Concern about poor crop weather in India is also supportive," Rijkers said. "There are also some background quality issues with the U.S. wheat crop which are also of concern."

CME Group Inc is likely to confirm quality problems in U.S. wheat supplies with new reports on plant fungus levels in grain delivered against futures contacts, traders said on Wednesday.

But prospects of larger U.S. sowings and of excellent South American harvests are limiting gains in corn and soybeans, Rijkers said.
