CIM23SAPP1A-11

CIM23SAPP1A-11 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 good seed parent yield.   General Information
  Target region Southern Africa
  Adaptation/Agroecological zone 400-1800 masl
  Type of product Three-way cross hybrid
  Year first announced 2024
     
  Why farmers say they like it*
      Good crop stand, Cob size, Disease tolerance
Grain Yield  
Grain yield under optimum conditions 10.71 t/ha   *Common keywords from farmer feedback (CIMMYT Southern Africa 2024 Stage 5 Trials)
Grain yield under managed drought 2.14 t/ha
