BEIJING, July 2 (Reuters) - Chicago corn futures edged higher on Thursday on bargain-buying ahead of a U.S. holiday weekend and support from bullish quarterly U.S. stocks data, while soybeans rose on hopes of renewed Chinese buying and robust domestic crush demand.

Wheat gained as smaller-than-expected acreage estimates for the United States and Canada supported prices.
