January is 6 cents higher at $6.90 1/4 and March is 6 1/2 cents higher at $7.03 1/4.

Wheat futures are mixed at midday. Light profit-taking is weighing on the CBOT after a firm open.

CBOT Mar is 1 cent lower at $5.18, KCBT Mar is 3 1/4 cents higher at $5.41, and MGE Mar is 1 1/2 cents higher at $5.25.
