U.S. wheat edged higher on Thursday as the grain drew some short-covering support, but prices continued to linger near the lowest since June 2010 amid silo-busting global supplies.

Corn and soybean were also higher, posting their second day of gains in six sessions.

The most active Chicago Board of Trade wheat contract rose 0.4 percent to $4.52 a bushel, up from a contract low of $4.42-1/2 hit on Wednesday. Prices rose nearly 1 percent in the previous session.

Despite increasing for two consecutive sessions - helped by fund buying and technical elements - fundamentals remained bearish, analysts said.

"The overall trend is still heavy with weather conditions that remain favorable at this stage of the year," French consultancy Agritel said.

Analysts noted some concerns over dry conditions emerging in the southern fringes of the U.S. Plains, although ample global supplies continue to drag on prices.

Despite the concerns, U.S. wheat production may hit record levels, one pillar of large global supplies that is expected to drive end-stocks for 2015/16 to an all-time high, the U.S. Department of Agriculture said.

On the demand side, the Taiwan Flour Millers' Association purchased 100,975 tonnes of U.S. milling wheat in a tender that closed on Thursday, European traders said.

In corn, the most active futures rose 0.14 percent to $3.56-3/4, having risen by a similar percentage in the previous session.

The South African government has estimated its maize crop at 7.2 million tonnes, but the country's largest grain producer group said it expected the forecast to be lowered.

The most active soybeans futures contract was little changed at $8.62 a bushel, having firmed 0.4 percent on Wednesday.

The USDA on Tuesday reported U.S. soyoil stocks at the end of January at 2.11 billion lbs, more than some analysts expected.
