Corn rebounded from a 35-month low on speculation that Midwest rains will miss most of Iowa, the biggest U.S. grower, further limiting growth of a crop that was planted later than normal. Soybeans and wheat also gained.
Wheat gained for the fifth time in six sessions as wet weather in Canada, the second-biggest shipper of the grain, may reduce planting to its lowest amount in almost four decades. Corn and soybean also rose.
Soybeans rose to a one-week high on speculation that wet weather in Great Plains and Midwest states will prevent U.S. farmers from seeding crops on already muddy fields. Corn rallied for the seventh of eight sessions.
