CZH15305

CZH15305 is a high-yielding, late-maturing maize hybrid with white grain that is nitrogen-use efficient, with resistance to GLS, TLB, ear rots, rust, and MSV, suitable for food use in tropical, rainfed, dry/wet mid- and upper-altitudes in southern Africa and similar agroecologies.    General Information   Adaptation/Agroecological zone 1000 - 2000 masl   Region Southern Africa   Type of product Three-way Cross   Year first announced 2018             Grain Characteristics Grain Yield   Grain color White Grain yield (HL) 9.3 t/ha   Grain texture Semi-flint Grain yield (WLMA) 9.2 t/ha       Grain yield (WUMA) 6.8 t/ha   Biotic Stress Performance Grain yield (DMA) 6.3 t/ha   Turcicum leaf blight (TLB) (1-9) (WLMA) 3.6 Grain yield (DLL) 5.3 t/ha   Rust (1-9) (WLMA) 2.4 Grain yield under low N stress 2.9 t/ha   Maize streak virus (MSV) (1-9) (WUMA) 1.4       Grey leaf spot (GLS) (1-9) (WLMA) 2.0 Agronomic Characteristics (WLMA)   Ear rot (WLMA) 1.8% Maturity 136 DAP   Diseases were originally scored on a 1-5 scale but have been converted here to a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
