* U.S. corn plantings near completion, weather benign
* Strong export demand helps to underpin soybean prices
* European trade slowed by public holidays in France, Germany (Adds quote, updates prices)
LONDON, June 5 (Reuters) - Chicago wheat futures were little changed on Monday, with hot and dry weather in the northern U.S. Plains underpinning the market while generally plentiful global supplies capped potential for stronger prices.
Corn and soybean futures were also barely changed.
The market has derived support from forecasts of warm and dry weather in the northern U.S. Plains, potentially stressing newly planted crops in the country's key region for spring wheat.
The Chicago Board of Trade's most-active wheat contract had eased 0.2 percent to $4.28-3/4 a bushel by 1104 GMT, having closed 0.1 percent up on Friday.
"Dryness and hot weather are causing concerns for the U.S. wheat crop. Adverse weather will continue to support wheat prices this week," said Kaname Gokon of Tokyo brokerage Okato Shoji.
The U.S. Department of Agriculture has rated 62 percent of the U.S. spring wheat crop as good to excellent, down significantly from 79 percent a year earlier.
December wheat in Paris was down 0.3 percent at 170.25 euros a tonne.
Dealers said that public holidays in several countries including France and Germany helped to slow activity in Europe.
The most-active CBOT corn contract was unchanged at $3.72-3/4 a bushel.
"Weather forecasters have a largely benign outlook for U.S. crops. Planting should be completed shortly on this outlook," Commonwealth Bank of Australia analyst Tobin said in a note.
"Chinas corn continues to experience dry weather. The issue is on the watch list but is not really a full blown problem for now. The market continues to trade a narrow range that has persisted for a few months."
The most-active CBOT soybean contract was unchanged at $9.21-1/4 a bushel.
Weekly USDA export sales data for soybeans came in above trade expectations and the government, through its daily reporting system, said that private exporters sold 200,000 tonnes of U.S. soybeans to drought-hit Spain.
But plentiful supplies capped gains in soybean markets.
Informa Economics, a private analytics specialist, on Friday raised its estimate of Brazil's 2016/17 soybean harvest to 114.5 million tonnes from the 113 million tonnes forecast last month, trade sources said.
It also raised its estimate for Argentina's 2016/17 soybean crop to 58 million tonnes from 56.8 million tonnes forecast previously. (Additional reporting by Naveen Thukral; Editing by Joseph Radford and David Goodman)
