* Adverse weather in Brazil and U.S. supports corn
* Soybeans, wheat up after two sessions of falls
CANBERRA, April 29 (Reuters) - U.S. corn futures edged higher on Thursday, recovering from a sharp drop in the previous session, as concerns over global supplies supported prices.
Soybeans and wheat also ticked higher after two straight sessions of falls.
The most-active corn futures on the Chicago Board of Trade were up 0.1% at $6.44-3/4 a bushel by 0415 GMT, after closing 1.6% lower on Wednesday.
Corn hit its highest level in nearly eight years earlier in the week, igniting profit-taking that saw prices fall more than 3% at one point on Wednesday.
Analysts said a correction was underway despite uncertainties about global production.
"Some investors quickly turned tail after prices soared," said Tobin Gorey, director of agricultural strategy, Commonwealth Bank of Australia. "It has passed now and we (are) in a watching brief for now."
Southern Brazil is forecast to stay dry into early May, but an expected warming of temperatures along with showers in the U.S. Midwest could help planting and early crop development.
Soybean futures were up 0.3% at $15.18-1/4 a bushel, having closed 0.4% lower on Wednesday.
Wheat futures rose 0.2% to $7.24-1/2 a bushel, having closed 1.4% lower on Wednesday.
Wheat, however, remains under pressure amid signs that major buyers are deferring purchases amid soaring prices.
Egypt's state grains buyer, the General Authority for Supply Commodities, said on Tuesday it had cancelled an international purchase tender for wheat for Aug. 11-20 shipment. (Reporting by Colin Packham; Editing by Subhranshu Sahu)
