CIM22LAPP1C-10

CIM22LAPP1C-10 is an intermediate-maturing, high-yielding, yellow maize hybrid with TSC, MLB and Ear rots resistance. The product is notable for its high optimum yield,  excellent synchrony, low ear position, semi-flint grain and resistance to root lodging and is suitable for feed use in tropical rainfed low-altitude areas in Latin America.   General Information
