CKDHH170013

CIMMYT's eastern Africa product pipeline 1A (EA-PP1A) focuses on developing intermediate maturing, white grain, high-yielding maize hybrids that are drought tolerant, resistant to GLS, TLB, ear rots, and MSV, and are suitable for food use in tropical rainfed dry/wet mid-altitude areas in eastern Africa.    General Information
  Adaptation/Agroecological zone 1000 - 1600 masl
  Type of product Three-way cross hybrid
  Year first announced 2018
     
  Grain Characteristics
      Grain color White
Grain Yield   Grain texture Semi flint
Grain yield under optimum conditions 6.7 t/ha      
Grain yield under random stress 2.9 t/ha   Biotic Stress Performance
Grain yield under drought stress 1.9 t/ha   Turcicum leaf blight (TLB) (1-9) 3.4
      Grey leaf spot (GLS) (1-9) 2.2
Agronomic Characteristics   Maize streak virus (MSV) (1-9) 0.8
Maturity 138 DAP   Common rust (1-9) 3.4
Plant height 228.6 cm   Diseases were originally scored on a 1-5 scale but have been converted here to a 1-9 scale, where 1 = Highly resistant; 5 = Tolerant; 9 = Highly susceptible.
Bad husk cover 5.4%  
Root lodging 2.0%  
Stalk lodging 13.0%      
Anther-silking interval 0.5 Days   Seed Production Characteristics
Ear aspect (1-5) 2.3   Nicking -0.5 Days
Plant aspect (1-5) 2.7      
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 various trials conducted by CIMMYT in eastern Africa in 2017.

Abbreviations:
DAP = days after planting
GLS = Grey Leaf Spot
Low N = Managed Low Nitrogen
masl = meters above sea level
