* Russian attack on Ukraine port supports wheat
* Soybeans dip on rains in Brazil
* Corn makes slight gains
CHICAGO, Nov 22 (Reuters) - Chicago wheat gained more than 1% on Wednesday as a Russian attack on a Ukrainian port continued to stoke worries over trade in the Black Sea, an integral route for the global grain market.
Soybeans declined as rains in Brazil eased concerns about unfavorable dryness, while corn ticked up.
The most-active wheat contract on the Chicago Board of Trade (CBOT) was up 6-1/2 cents to $5.89-1/4 a bushel at 10:20 a.m. CST (1620 GMT), after earlier reaching $5.91-1/2, its highest price since Nov. 9.
Russia's strike on port infrastructure in Ukraine's southern city of Odesa on Tuesday rekindled concerns over Kyiv's recently established wartime shipping channel through the Black Sea.
"It still shows that's something that is a risk," said Angie Setzer, partner at Consus Ag Consulting. "Some folks are saying the more that you see Russia hit Ukraine in these little ways, the higher the risk that Ukraine fires back and does something to limit Russian exports."
Russia is the world's biggest wheat exporter, and Ukraine is a major shipper of corn and wheat.
The wheat market also found support after the U.S. Department of Agriculture confirmed sales of 110,000 metric tons of U.S. soft red winter wheat to China in the 2023/24 marketing year.
CBOT soybeans fell 6-1/2 cents to $13.70-3/4 a bushel, and corn inched up 2-3/4 cents to $4.72-3/4 a bushel.
In Brazil, the world's top soybean exporter, showers this week were expected to give Brazilian growing belts "modest relief," before hot, crop-stressing conditions return next week, Commodity Weather Group said.
"You're really not going to encourage a lot of folks to come in and go long when you have rain falling across a lot of the crop area," Setzer said.
Brazil's soybean crop is expected to reach a record 161.6 million metric tons in 2023/24, agribusiness consultancy Agroconsult said, despite weather issues.
