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.

art. inoc. = artificial inoculation
DAP = Days after planting
GLS = Grey leaf spot
HD = High density (80,000 plants per ha)
LGB = Large grain borer
Low N = Managed low nitrogen
masl = meters above sea level
MD = Managed drought
MSV = maize streak virus
MLN = Maize lethal necrosis
MW = Maize weevil
NUE = Nitrogen use efficient
OPT = Optimum management
RS = Random stress
TLB = Turcicum leaf blight
