CKDHH170066

CIMMYT's eastern Africa product pipeline 1A (EA-PP1A) focuses on developing intermediate maturing, white grain, high-yielding maize hybrids that are drought tolerant, NUE, 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 6.6 t/ha      
Grain yield under random stress 2.8 t/ha   Biotic Stress Performance
Grain yield under drought stress 0.9 t/ha   Turcicum leaf blight (TLB) (1-9) 2.8
      Grey leaf spot (GLS) (1-9) 2.4
Agronomic Characteristics   Maize streak virus (MSV) (1-9) 0.8
Maturity 135 DAP   Common rust (1-9) 2.6
Plant height 221.9 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 5.7%  
Root lodging 0.9%      
Stalk lodging 10.4%   Seed Production Characteristics
Anther-silking interval 1.6 Days   Nicking 2.0 Days
Ear aspect (1-5) 2.5      
Plant aspect (1-5) 2.7   Comments
Plant and ear aspects are scored on 1-5 scale, where 1 = desirable and 5 = undesirable characteristics   Product information is based on data from various trials conducted by CIMMYT in eastern Africa in 2018.

Abbreviations:
DAP = days after planting
GLS = Grey Leaf Spot
masl = meters above sea level
MSV = maize streak virus
TLB = Turcicum Leaf Blight
