CANBERRA, April 29 (Reuters) - Chicago wheat futures edged lower on Monday but remained near four-month highs after concerns that adverse weather conditions in Russia, Europe and the United States could reduce supply pushed prices up around 10% last week.

Corn and soybean prices were little changed.
