  1. a Greenhouse location: Canada (Delta, British Columbia), Mexico (Jocotitlan, Mexico) and USA (Marfa, Texas). The number inside each parenthesis represents the number of PepMV isolates in that genotype/total number of samples submitted by growers for PepMV identification and genotype examination.
  2. b nt: not tested.
