Wheat futures edged up as the U.S. Department of Agriculture pegged the condition of the domestic crop below market expectations, stoking fears of production losses following recent adverse weather. The most active wheat futures on the Chicago Board of Trade rose 0.35 percent to $4.31 a bushel, having closed little changed on previous close. The USDA rated 55 percent of the U.S. spring wheat crop in good-to-excellent condition, down from 62 percent a week earlier.
