CIM20ADTY-70

CIM20ADTY-70 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 stable-performance hybrid with excellent seed production characteristics and improved disease tolerance (TLB), suited for variable and stress-prone regions.   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.) 7.14 t/ha   Fusarium stalk rot (FSR) (AI) (1-9)* 5.2 Grain yield (rainfed) 4.44 t/ha   Turcicum leaf blight (TLB) (AI) (1-9)* 3.7 Grain yield under on-farm conditions 7.13 ± 0.51 t/ha   Ear Rots (%) 4.3 Grain yield under drought stress (DT) 3.75 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 4.86 t/ha 906 GDD   Male parent yield 4.42 t/ha Anthesis-silking interval  0.50 days   Nicking 0.0 days Ear height  38 cm       Plant height  75 cm   Comments Ear position (ratio) 0.50   Product information is based on data from CIMMYT's 2022-23 Stage 4 and 2024-25 Stage 5 Trials under SADT.
