  1. LSS: lowland severe stress; LMS: lowland moderate stress; LNS: lowland non-stress, UMiS: upland mild stress.
  2. means ± SED (M), broad-sense heritability (H), P values (P), and percentage yield reduction (YR) for grain yield (GY, in kg ha-1), days to 50% flowering (DTF), and plant height (PH, in cm).
  3. a: probability of difference between genotypes; *, ****: significant at 5%, and 0.01% P levels, respectively; b: compared with the DS2012 LNS trial.
