CHICAGO, April 22 (Reuters) - Chicago Board of Trade wheat futures ended slightly lower on Tuesday as the U.S. dollar fell and winter wheat conditions were shown declining, according to the U.S. Department of Agriculture.
CBOT July soft red winter wheat WN25 settled down 2 cents to $5.50-1/4 per bushel.
K.C. July hard red winter wheat KWN25 ended down 5-1/2 cents to $5.58-1/4 a bushel and Minneapolis July spring wheat MWEN25 fell 3-3/4 cents to settle at $6.10-1/4 a bushel.
The USDA reported 45% of winter wheat was in good or excellent condition in a weekly crop report after crops in the Plains have struggled with dryness. Analysts on average expected a rating of 47%. A year ago, half of the crop was rated good or excellent.
For spring wheat, planting was 17% complete, exceeding the five-year average of 12% and analysts' estimates for 13%, the USDA said. A week ago, 7% of the crop was planted.
The dollar hovered around multi-year lows versus the euro and the Swiss franc on Tuesday as President Donald Trump's attacks on the Federal Reserve raised concerns about the central bank's independence.
Doubts about Fed independence threaten the dollar's value as a reserve currency, with analysts noting possible divestments from what many consider over-exposure to U.S. assets.
A weaker dollar makes U.S. exports cheaper and more competitive on the global market.
