CIM24SAPP2-18

CIM24SAPP2-18 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.   General Information   Target region Southern Africa   Target region <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 9.62 t/ha   Biotic Stress Performance Grain yield under managed drought stress 2.13 t/ha   Turcicum leaf blight (TLB) (1-9) 4.6 Grain yield under low N stress 2.6 t/ha   Grey leaf spot (GLS) (1-9) 4.0 Grian Yield on-farm (moderate stress) 5.65  t/ha   Maize Streak Virus (MSV) (1-9) 3.7 Grain Yield on-farm (severe stress) 1.90  t/ha   Ear rots 8.1%       Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
