CBOT Trends-Wheat up 1-3 cents, corn and soybeans up 2-4 cents

CHICAGO, April 27 (Reuters) - The following are U.S. expectations for the resumption of grain and soy complex trading at the Chicago Board of Trade at 8:30 a.m. CDT (1330 GMT) on Monday:

WHEAT - Up 1 to 3 cents per bushel

• Wheat firmed on higher crude oil prices and a weaker U.S. dollar. Gains limited by crop-boosting rains in the U.S. Plains wheat belt.

• Periods of rain over the next two weeks in the Plains are due to bring relief to the drought-hit crop, Commodity Weather Group said. But the forecaster said up to a third of the winter wheat crop would remain stressed in the near term.

• Saudi Arabia's main state buying agency said that it bought 985,000 metric tons of wheat in an international tender.

• CBOT July soft red winter wheat WN26 was last up 2-1/4 cents at $6.19 per bushel. K.C. July hard red winter wheat KWN26 was last down 1-3/4 cents at $6.68 per bushel, and Minneapolis July spring wheat MWEN26 traded unchanged at $6.93-1/4 per bushel.

CORN - Up 2 to 4 cents per bushel

• Corn futures edged up on rising crude oil prices and as rain in the Midwest stalled planting.

• Benchmark July corn CN26 held technical chart support at its 50-day moving average and climbed to its highest point since April 3 during overnight trading.

• Midwest rains are expected to taper by the middle of the week so farmers are unlikely to remain sidelined for long.

• CBOT July corn CN26 was last up 3 cents at $4.66-1/2 per bushel.

SOYBEANS - Up 2 to 4 cents per bushel

• Soybeans firmed on higher crude oil and as rainy weather delayed planting in the Midwest. Gains capped by ample supplies from bumper harvests in South America.

• CBOT July soybeans SN26 were last up 2-1/2 cents at $11.81 per bushel.
