Weakness in the dollar added support to wheat.
Traders noted bargain buying after the benchmark Chicago Board of Trade soft red winter wheat contract hit its lowest since Feb. 8 on Tuesday.
US soft white wheat was the cheapest wheat offered, excluding shipping costs, in an Egyptian government tender for supplies, traders said.
Analysts were expecting a US Agriculture Department report on Thursday morning to show export sales of wheat in the latest week were in a range from 275,000 tonnes to 650,000 tonnes (new-crop and old-crop combined.) That compares with a combined 431,584 tonnes a week earlier.
