CIM22LAPP1A-10

CIM22LAPP1A-10  is an intermediate-maturing, high-yielding, white maize hybrid with resistance to TSC, MLB and ear rots. The product is notable for its high optimum and rainfed yield, excellent female parent seed yield, semi-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 Semi-dent Abiotic Stress Performance       Grain yield under optimum conditions 8.78 t/ha   Biotic Stress Performance Grain yield under rainfed conditions 4.99 t/ha   Maydis leaf blight (MLB) (1-9)* 2.5 Grain yield on-farm (avg) 7.24 t/ha   Tar Spot Complex (TSC) (1-9)* 2.9 Grain yield on-farm (opt.) 9.10 t/ha   Ear Rots (%) 7.3% Grain yield on-farm (rainfed) 5.48 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  57 DAP   SC female parent seed yield  7.9 t/ha Plant height 244 cm   Male seed yield  3.6 t/ha Ear height 127 cm   Nicking -6 days Ear position (ratio) 0.52       Ears per plant 1.02   Comments Ear aspect (1-9)* 4.2   Product information is based on data from the 2022 CIMMYT LatAm Stage 4 Regional Trials and 2023 Stage 5 Trials.
