| CIM20LAPP2B-12 is an intermediate-maturing, high-yielding, yellow maize hybrid with resistance to GLS, TLB and ear rots. The product is notable for its good husk cover, ear position, standability and is suitable for feed use in the central mid-altitude environments of Mexico or similar agro-ecologies in other regions. |
