CHICAGO, June 11 (Reuters) - U.S. wheat futures rallied

on Tuesday after a nine-session slide, with the benchmark

Chicago Board of Trade (CBOT) July wheat contract lifted

by bargain buying and renewed worries about crops in top global

exporter Russia, brokers said.

CBOT soybean and corn futures declined as market players

awaited fresh direction from monthly crop supply/demand reports

due on Wednesday from the U.S. Department of Agriculture.

As of 12:58 p.m. CDT (1758 GMT), CBOT July wheat was

up 18-1/2 cents at $6.26 per bushel, bouncing after a dip to

$6.05-1/2, the contract's lowest since May 3. Technical traders

noted chart support at the contract's 100-day moving average

near $6.04.

CBOT July soybeans were down 9 cents at $11.79-1/4 a

bushel and July corn was down 1-1/4 cents at $4.50-1/2 a

bushel.

Wheat jumped after the head of Russia's grain union said

frosts in Russia have affected between 15% and 30% of winter

grains, varying by region, a much higher figure than suggested

by the agriculture ministry.

Benchmark CBOT wheat had fallen more than $1 a bushel since

May 28, pressured by the start of the Northern Hemisphere winter

wheat harvest and a temporary ban on imports by major buyer

Turkey.

Some saw the market as over-sold and due for a bounce,

especially given the news about Russian frost damage and a

surprise drop in U.S. winter and spring wheat condition ratings.

"The recent sharp fall in wheat prices was partly attributed

to the rapid progress of the harvest in the USA," Commerzbank

said in a note. "However, it is still too early to draw

conclusions about the ongoing harvest."

Fresh export business lent support. Top buyer Egypt booked

460,000 metric tons of Black Sea-origin wheat in an

international tender.

CBOT soybean futures declined but held above a one-month low

set earlier this week, and corn futures were choppy as traders

awaited the USDA's monthly reports on Wednesday. Analysts

surveyed by Reuters on average expect the USDA to raise its

forecasts of U.S. 2023/24 and 2024/25 soybean ending stocks, and

lower its forecasts for corn inventories.

Meanwhile, the U.S. corn and soybean crops are off to a

strong start. The USDA late Monday rated 74% of the U.S. corn

crop in "good-to-excellent" condition, down a point from last

week but still the highest for this time of year since 2020.

Soybeans were rated 72% "good-to-excellent" in the USDA's

first ratings of 2024 for the oilseed, in line with trade

expectations.
