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 600-1800 masl   Type of product Three-way cross hybrid   Year first announced 2017         Grain Characteristics   Grain color White       Grain texture Semi-flint Grain Yield   Oil content 6.3% Grain yield under optimum conditions 7.7 t/ha   Starch content 68.5% Grain yield under MSV stress 6.6 t/ha   Protein content 10.1% Grain yield under low N stress 1.6 t/ha   Lysene content 0.45% Grain yield under random stress 4.3 t/ha   Tryptophane content 0.10%           Agronomic Characteristics     Biotic Stress Performance Maturity Intermediate   Turcicum leaf blight (TLB) (1-9)* 2.2 50% anthesis 68 DAP   Grey leaf spot (GLS) (1-9)* 2.4 Anthesis-silking interval 1.3 days   Common rust (P.
