CZH15149

CZH15149 is a late-maturing, white-grain, high-yielding, drought-tolerant maize hybrid that is resistant to rust, GLS, and TLB, and 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 Single-cross hybrid   Year first announced 2016             Grain Characteristics Grain Yield   Grain color White Grain yield under HD 9.52 t/ha       Grain yield under opt (ME-A) 7.75 t/ha   Biotic Stress Performance Grain yield under random stress (ME-C) 4.10 t/ha   Grey leaf spot (GLS) (1-9)* 3.4 Grain yield under low N stress 1.85 t/ha   Common rust (P. sorg) (1-9)* 2.0       Turcicum leaf blight (TLB) (1-9)* 1.2 Agronomic Characteristics   *Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
