CZH15075

CZH15075 is a late-maturing, white-grain, high-yielding, drought-tolerant maize hybrid that is resistant to GLS, TLB, Ear rots, 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 2016             Grain Characteristics Grain Yield   Grain color White Grain yield under opt (ME-A) 8.85 t/ha   Grain texture Dent Grain yield under HD (ME-A) 10.02 t/ha       Grain yield under opt (ME-B) 7.45 t/ha   Biotic Stress Performance Grain yield under random stress (ME-C) 5.37 t/ha   Grey leaf spot (GLS) (1-9)* 3.2 Grain yield under opt (ME-D) 3.49 t/ha   Common rust (P. sorg) (1-9)* 2.2 Grain yield under low N stress 3.50 t/ha   Turcicum leaf blight (TLB) (1-9)* 2.2 Grain yield under low pH stress 4.51 t/ha   *Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
