CAH1511

­

CAH1511 is an intermediate-maturing maize hybrid bred for the tropical lowlands of South Asia. This high-yielding, yellow-kernel maize hybrid performs well under drought and drought-plus-waterlogging conditions, and has tolerance to TLB, FSR and BLSB.   General Information   Target Region South Asia   Adaptation/Agroecological zone Tropical Lowland   Type of product Single-cross hybrid   Year first announced 2015             Kernel Characteristics Grain Yield   Kernel color Yellow Grain yield (opt.) 9.77 t/ha   Kernel texture Semi-dent Grain yield under drought stress (DT) 3.40 t/ha       Grain yield under waterlogging stress (WL) 6.46 t/ha   Biotic Stress Performance Grain yield random stress (RS) 2.94 t/ha   Fusarium stalk rot (FSR) (AI) (1-9) 6.5       Turcicum leaf blight (TLB) (AI) (1-9) 5.6 Agronomic Characteristics   Banded leaf and sheath blight (BLSB) (AI) (1-9) 5.6 50% anthesis 51.2 Days   Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible. Anthesis-silking interval  2.2 Days   Ear height  80.9 cm       Plant height  177.7 cm   Seed Production Characteristics Ears per plant 0.97   Female parent yield 3.6 t/ha Bad husk cover 4.5%   Male parent yield 2.8 t/ha Ear aspect (1-5) 2.0   Nicking  3 days Plant aspect (1-5) 2.2       Plant and ear aspects are scored on 1-5 scale, where 1 = desirable and 5 = undesirable characteristics   Comments   Product information is based on data from the CIMMYT South Asia 2020 Regional Trial (SAWLDT) and 2021 regional on-farm trials (ROFT 2021-1A). Actual performance will vary depending on a number of agronomic and environmental factors.
