CIM20LAPP2B-12

CIM20LAPP2B-12  is an intermediate-maturing, high-yielding, yellow maize hybrid with resistance to GLS, TLB and ear rots. The product is notable for its good husk cover, ear position, standability and is suitable for feed use in the central mid-altitude environments of Mexico or similar agro-ecologies in other regions.   General Information   Target Region Latin America   Adaptation/Agroecological zone 1200 - 1800m above sea level   Type of product Three-way hybrid   Year first announced 2023         Grain Characteristics   Grain color Yellow       Grain texture Semi-dent Abiotic Stress Performance       Grain yield in Stage 4 trials  8.4 t/ha   Biotic Stress Performance Grain yield on-farm 8.9 t/ha   Turcicum leaf blight (TLB) (1-9)* 3.4       Grey leaf spot (GLS) (1-9)* 3.0 Agronomic Characteristics   Curvularia Leaf Spot (CLS) (1-9)* 3.0 Maturity group Intermediate   Maydis Leaf Blight (MLB) (1-9)* 2.3 50% anthesis 71 DAP   Ear Rots (%) 6.7% Anthesis-silking interval 0.7 days   Fusarium Stalk Rots (FSR) (%) 19.2% Plant height 250 cm   *Scored on 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible Ear height 131 cm   Ear position (ratio) 0.52       Ears per plant 1.01   Seed Production Characteristics Ear aspect (1-9)* 4.0   SC female parent seed yield  11.6 t/ha Plant aspect (1-9)* 4.1   Male seed yield  5.0 t/ha Bad husk cover 2.4%   Nicking 0 days Root lodging 6.3%       Stalk lodging 7.0%   Comments *Plant and ear aspects are scored on 1-9 scale, where 1 = desirable and 9 = undesirable characteristics   Product information is based on data from the 2021 CIMMYT Mexico Stage 4 Trials and 2022 Stage 5 Trials.
