JAKARTA: Chicago corn climbed for a fifth straight session on Tuesday amid reports of a delay in the US planting season, while soybeans and wheat retreated from multi-months highs.

Corn prices rose on the back of unexpected supply shortage, as volatile weather hit top producers US and Brazil, while Argentina struggled with insect infestation in corn producing areas, a trader said.

The most-active corn contract on the Chicago Board of Trade (CBOT) gained 0.11% to $4.69-1/2 a bushel by 0248 GMT, hitting the highest since Dec. 29.

Wheat was down 0.15% to $6.47-3/4 a bushel after hitting a nine-month high earlier in the day, while soybeans lost 0.18% to $12.46-1/2 a bushel.
