CIM20ADTY-66

CIM20ADTY-66 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 conditions, and has tolerance to TLB and FSR. It is a top-performing, high-yield hybrid under optimal conditions (8.06 t/ha) with broad adaptability, suitable for high-input environments.   General Information   Target Region South Asia   Adaptation/Agroecological zone Tropical Lowland   Type of product Single-cross hybrid   Year first announced 2026         Kernel Characteristics   Kernel color Yellow   Kernel texture Semi-flint           Grain Yield   Biotic Stress Performance Grain yield (opt.) 8.06 t/ha   Fusarium stalk rot (FSR) (AI) (1-9)* 5.0 Grain yield (rainfed) 4.62 t/ha   Turcicum leaf blight (TLB) (AI) (1-9)* 5.3 Grain yield under on-farm conditions 7.11 ± 0.52 t/ha   Ear Rots (%) 5.0 Grain yield under drought stress (DT) 3.68 t/ha   *Diseases are scored on a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.       Agronomic Characteristics       Maturity group Intermediate   Seed Production Characteristics 50% anthesis 57 days   Female parent yield 3.37 t/ha 906 GDD   Male parent yield 5.39 t/ha Anthesis-silking interval  0.56 days   Nicking -2.0 days Ear height  41 cm       Plant height  78 cm   Comments Ear position (ratio) 0.52   Product information is based on data from CIMMYT's 2022-23 Stage 4 and 2024-25 Stage 5 Trials under SADT.
