CKDHH170002

CIMMYT's eastern Africa product pipeline 1B (EA-PP1B) focuses on developing high-yielding, early maturing maize varieties with white grain, drought tolerance, and resistance to GLS, TLB, and ear rots, that are suitable for food use in tropical, rainfed, dry, mid-altitude areas in eastern Africa and similar agroecologies.    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 texture Semi dent
         
Grain Yield   Biotic Stress Performance
Grain yield under optimum conditions 7.2 t/ha   Turcicum leaf blight (TLB) (1-9) 2.5
Grain yield under random stress 3.4 t/ha   Grey leaf spot (GLS) (1-9) 2.6
Grain yield under drought stress 3.0 t/ha   Common rust (1-9) 2.6
      Ear Rots 12.4%
Agronomic Characteristics   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.
Maturity 132 DAP  
Plant height 240.5 cm  
Bad husk cover 4.2%      
Root lodging 12.4%   Seed Production Characteristics
Stalk lodging 10.2%   Nicking -1 Days
Anther-silking interval 1.5 days      
Ear aspect (1-5) 2.5   Comments
Plant aspect (1-5) 2.4   Product information is based on data from various trials conducted by CIMMYT in eastern Africa in 2017.

Abbreviations:
DAP = days after planting
FAW = Fall armyworm
GLS = Grey Leaf Spot
HD = High Density (80,000 plants per ha)
Low N = Managed Low Nitrogen
masl = meters above sea level
MD = Managed drought
MSV = maize streak virus
NUE = Nitrogen Use Efficient
Opt = Optimum Management
TLB = Turcicum Leaf Blight
Plant and ear aspects are scored on 1-5 scale, where 1 = desirable and 5 = undesirable characteristics
