    SINGAPORE/PARIS, July 21 (Reuters) - Chicago wheat rose for
a sixth consecutive session on Wednesday as adverse weather in
key exporting countries raised supply concernswhile soybeans
edged lower on weaker oil prices and slowing demand in top
importer China.
    Corn was flat. 
    "There are definitely problems for the U.S. and spring wheat
crops but we will get to know how big the problem is when the
harvest starts, which is about two weeks from now for the U.S.
spring wheat and Canada is about a month later," said one
Singapore-based trader, who sells U.S. wheat to millers in Asia.
    The most-active wheat contract on the Chicago Board Of Trade
(CBOT) climbed 0.4% to $7.03-1/4 a bushel by 1130 GMT,
having risen to $7.10 a bushel earlier in the session and
touching a May 18 high of $7.18 a bushel on Tuesday. 
    Soybeans lost 0.4% to $13.82-1/2 a bushel, while corn
 was unchanged at $5.65-3/4 a bushel.
    The wheat market is being underpinned by crop concerns in
North America and the Black Sea region.
    The U.S. Department of Agriculture (USDA), in a report
released after Monday's market close, rated 11% of U.S. spring
wheat as good or excellent, down from 16% a week earlier and
below analysts' average estimate of 15%.

    The USDA last week projected that U.S. spring wheat
production would shrink to a 33-year low.
    The agency left unchanged its good/excellent score for U.S.
corn at 65%, short of an analyst consensus of 66%. It raised the
soybean rating by 1 percentage point to 60%, in line with
    China's soybean imports from Brazil slipped in June from a
year earlier, customs data showed on Tuesday, as poor crushing
margins weighed on demand.
    Declining soybean crush margins have hit China's demand,
which has been strong in recent months as the country's
recovering pig herd boosted consumption.

soyoil, wheat and soymeal futures contracts on Tuesday, traders
