  1. aThe numeral within parentheses indicates the number of plants that did not receive sufficient inoculum and therefore escaped infection. Those plants were not considered for pathogenicity scoring
  2. bThe first numeral within the square brackets indicates the number of plants in which more than 50% of the leaf/petiole was covered with pustules, and the second indicates the number of plants in which fusion of pustules was observed
  3. cData given for the first 100 plants tested
