  1. F test: probability level; ***, ** and * significant at p = 0.01, 0.05, and 0.10; ns = not significant. LSD g refers to significant differences in genotypes
  2. Means followed by the same letters are not significantly p < 0.01
  3. Yrefers to varieties under evaluation, that is, they were just tested but not yet released
  4. Yields indicated in bold font highlight the top yielding varieties per location
  5. @represents local checks per location, which are as follows: Mwea = Basmati 370, Ahero = IR 2793–80-1, Kirogo-Basmati 370, Bunyala = IR 2793–80-1, and, West Kano = IR 2793–80-1
