CZH15266

CZH15266 is a late-maturing, white-grain, high-yielding, drought-tolerant maize hybrid that is NUE and resistant to GLS, TLB, rust, and MSV, bred for food use in tropical, rainfed, dry/wet mid-altitude and transition ecologies in southern Africa and similar agroecologies.     General Information   Target region Southern Africa   Adaptation/Agroecological zone 400-1800 masl   Type of product Three-way cross hybrid   Year first announced 2017             Grain Characteristics Grain Yield   Grain color White Grain yield under HD (ME-A) 11.6 t/ha   Grain texture Semi-flint Grain yield under opt  (ME-A) 8.8 t/ha       Grain yield under opt (ME-B) 7.7 t/ha   Biotic Stress Performance Grain yield under opt (ME-C) 5.7 t/ha   Grey leaf spot (GLS) (1-9)* 3.0 Grain yield under opt (ME-D) 3.6 t/ha   Common rust (P. sorg) (1-9)* 2.6 Grain yield under MSV stress (ai) 8.1 t/ha   Turcicum leaf blight (TLB) (1-9)* 2.8 Grain yield under low N stress 2.4 t/ha   Ear rots 12.8%       *Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
