  1. Details of blast and RYMV scores are detailed in the Standard Evaluation system for rice (SES) (Mano et al. 2022)
  2. In brief, RYMV Score 1 represents high RYMV resistance, score 3 represents moderate RYMV resistance while scores 5,7 and 9 represent low RYMV resistance
  3. Pertaining blast score scales, score 0 represents high blast resistance; scores 1 to 3 represent moderate blast resistance; scores 4 to 9 represent low to no blast resistance, affecting from less than 4% (score 4) to more than 75% leaf area (score 9)
  4. @represents local checks per location, as follow: Mwea = Basmati 370, Ahero = IR 2793-80-1, Kiorogo = Basmati 370, Bunyala = IR 2793-80-1, and, west Kano = IR 2793-80-1
