CIM22LAPP1A-11

CIM22LAPP1A-11 is an intermediate-maturing, high-yielding, white maize hybrid with resistance to TSC, MLB and ear rots. The product is notable for its high rainfed yield, excellent female parent seed yield, dent grain and resistance to root and stalk lodging and is suitable for food use in tropical, rainfed, low-altitude areas in Latin America.   General Information   Target Region Latin America   Adaptation/Agroecological zone 0 - 1200m above sea level   Type of product Three-way hybrid   Year first announced 2024         Grain Characteristics   Grain color White       Grain texture Dent Abiotic Stress Performance       Grain yield under optimum conditions 8.70 t/ha   Biotic Stress Performance Grain yield under rainfed conditions 5.11 t/ha   Maydis leaf blight (MLB) (1-9)* 2.7 Grain yield on-farm (avg)  7.07 t/ha   Tar Spot Complex (TSC) (1-9)* 3.2 Grain yield on-farm (opt.)  8.73 t/ha   Ear Rots (%) 6.9% Grain yield on-farm (rainfed) 5.54 t/ha   *Scored on 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible       Agronomic Characteristics       Maturity group Intermediate   Seed Production Characteristics 50% anthesis  58 DAP   SC female parent seed yield   8.8 t/ha Plant height  241 cm   Male seed yield   4.5 t/ha Ear height  126 cm   Nicking -5 days Ear position (ratio) 0.52       Ears per plant 1.03   Comments Ear aspect (1-9)* 4.3   Product information is based on data from the 2022 CIMMYT LatAm Stage 4 Regional Trials and 2023 Stage 5 Trials.
