CIM22LAPP1A-10

CIM22LAPP1A-10  is an intermediate-maturing, high-yielding, white maize hybrid with resistance to TSC, MLB and ear rots. The product is notable for its high optimum and rainfed yield, excellent female parent seed yield, semi-dent grain and resistance to root and stalk lodging and is suitable for food use in tropical, rainfed, low-altitude areas in Latin America.   General Information
