GRAINS-Wheat edges lower, losses checked by concerns for U.S. crop

SYDNEY, Dec 28 (Reuters) - U.S. wheat fell on Thursday, edging lower after posting gains of more than 1 percent in the previous session, although losses were checked by concerns that unfavourable weather across the United States may damage crops.
