CZH15098Q

CZH15098Q is a high-yielding, early-maturing, nutritious maize hybrid with enhanced protein content, white grain, that is drought- and acid soil-tolerant, NUE, and resistant to rust and TLB, bred for food/feed use in tropical, rainfed, dry/wet mid-altitude and lowland ecologies in southern Africa and similar agroecologies. Quality Protein Maize (QPM) is an affordable option for alleviating protein malnutrition and reducing animal feed costs. QPM looks and tastes the same as normal maize but contains higher levels of the essential amino acids lysine and tryptophan. Eating QPM is especially beneficial for children who survive on a maize-dominated diet.    General Information   Target region Southern Africa   Adaptation/Agroecological zone < 1800 masl   Type of product Three-way cross hybrid   Year first announced 2016         Grain Characteristics   Grain color White   Grain texture Semi-dent         Biotic Stress Performance   Grey leaf spot (GLS) (1-9)* 5.4   Common rust (P. sorg) (1-9)* 1.8   Turcicum leaf blight (TLB) (1-9)* 3.0       Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible. Grain Yield   Grain yield under optimum conditions 6.59 t/ha       Grain yield under random stress 4.01 t/ha   Comments Grain yield under low N stress 3.66 t/ha   Product information is based on data from CIMMYT southern Africa 2016 regional trial (ADVQPM16).
