CANBERRA- Chicago wheat futures regained some ground on Tuesday after an easing of fears over supply from the Black Sea region triggered profit-taking in the previous session and pulled prices down from near three-month highs.

Corn and soybean futures were little changed as the United States ramps up what are expected to be bumper harvests, cementing expectations of plentiful supply.

The most active wheat contract on the Chicago Board of Trade (CBOT) was up 0.6 percent  at $5.82 a bushel, while CBOT corn edged 0.1 percent  higher to $4.11-1/4 a bushel and soybeans were flat at $10.04-3/4 a bushel.

Ample supply drove all three contracts to four-year lows in recent weeks but prices have recovered a little ground.

Wheat rallied to $5.99 on Friday, its highest since June 19, driven by crop losses in Europe, dry weather in Russia and Ukraine, a weak US dollar and a missile attack on a grain vessel in the Black Sea that Kyiv blamed on Moscow.

However, the absence of further escalation between Ukraine and Russia and confirmation that large amounts of wheat continue to flow from Russian and Ukrainian ports have tempered concerns, with prices falling 2.7 percent  on Monday.

“The main driver higher is dry weather in Ukraine and Russia heading into winter planting,” said Commonwealth Bank analyst Dennis Voznesenski, adding that speculators had reduced their bearish position in wheat.
