CIM24SAPP1-L-13

CIM24SAPP1-L-13 is a high-yielding, late-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 and having good male parent seed yield.    General Information   Target region Southern Africa   Adaptation/Agroecological zone 400-1800 masl   Type of product Three-way cross hybrid   Year first announced 2025         Grain Characteristics   Grain color White       Grain texture Semi-dent Grain Yield       Grain yield under optimum conditions 10.37 t/ha   Biotic Stress Performance Grain yield under managed drought 3.43 t/ha   Turcicum leaf blight (TLB) (1-9)* 4.7 Grain yield under low nitrogen 2.43 t/ha   Grey leaf spot (GLS) (1-9)* 3.7 Grain Yield on-farm (moderate stress) 5.43 t/ha   Maize Streak Virus (MSV) (1-9)* 3.7 Grain Yield on-farm (severe stress) 2.08 t/ha   Ear rots 9.4%       *Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
