CZH141029

CZH141029 is a high-yielding, intermediate-maturing maize hybrid with white grain, drought tolerance that is resistant to GLS, TLB, ear rots, and MSV, suitable 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 color White Grain Yield   Grain texture Semi-flint Grain yield under opt (ME-A) 9.09 t/ha       Grain yield under HD (ME-A) 11.25 t/ha   Biotic Stress Performance Grain yield under opt (ME-B) 5.88 t/ha   Turcicum leaf blight (TLB) (1-9)* 1.8 Grain yield under random stress (ME-C) 3.23 t/ha   Grey leaf spot (GLS) (1-9)* 2.4 Grain yield under opt (ME-D) 2.93 t/ha   Common rust (P. sorg) (1-9)* 2.2 Grain yield under low N stress 2.27 t/ha   Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible. Grain yield under low pH stress 4.39 t/ha   Grain Yield under low P stress 7.46 t/ha             Comments Agronomic Characteristics   Product information is based on data from CIMMYT southern Africa 2016 regional trial (IHYB16). Actual performance will vary depending on a number of agronomic and environmental factors.
