Ear height 108.8 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.
Plant aspect (1-5) 2.3  
Plant height 216.0 cm      
Root lodging 2.3%   Seed Production Characteristics
Stalk lodging 8.2%   Nicking 0 Days
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 2016.
