CIM20LAPP1C-9

CIMMYT's Latin America product pipeline Tropical Lowland (LatAm-PP1C) focuses on developing intermediate-maturing, yellow-grain, high-yielding maize hybrids that are drought tolerant, resistant to MLB and ear rots, and are suitable for feed use in tropical rainfed dry/wet low-altitude areas in Latin America.   General Information   Region Latin America   Adaptation/Agroecological zone 0 - 1200m above sea level   Type of product Three-way hybrid   Year first announced 2022             Grain Characteristics Grain yield   Grain color Yellow Grain yield under optimum conditions 7.5 t/ha   Grain texture Semi-dent Grain yield under rainfed conditions 6.0 t/ha       Grain yield on-farm  6.6 t/ha   Biotic Stress Performance Grain yield under drought stress 3.7 t/ha   Maydis leaf blight (MLB) (1-9) 3.4       Tar Spot Complex (TSC) (1-9) 5.4 Agronomic Characteristics   Diseases are scored on 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible 50% anthesis 56 DAP   Plant height 250 cm       Ear height 119 cm   Seed Production Characteristics Ear position (ratio) 0.47   Female seed yield  6.0 t/ha Ears per plant 1.0   Male seed yield  3.3 t/ha Ear aspect* 2.3   Nicking 5 days Bad husk cover 1.7%       Ear rot  6.6%   Comments Root lodging 4.1%   Product information is based on data from the 2020 CIMMYT LatAm Stage 4 Regional Trials and 2021 Stage 5 trials.
