| CIM23SAPP1A-02 is a high-yielding, intermediate maturing maize hybrid with white grain, that is drought tolerant, NUE, and resistant to GLS, TLB, ear rots, and MSV. It is suitable for cultivation for food use in tropical, rainfed, dry/wet mid-altitude and transition ecologies in southern Africa and similar agroecologies. It is especially notable for yielding multiple ears per plant. |
