| CIM22SAPP2-10 is a high-yielding, early-maturing maize hybrid with white grain, that is drought tolerant, NUE, and resistant to GLS, MSV, and TLB. It is suitable for cultivation for food use in tropical, rainfed, dry/wet mid-altitude and lowland ecologies in southern Africa and similar agroecologies. It has demonstrated good nicking and comparatively good yield under severe stress. |
