  1. Values are means of 5 replicates
  2. Values with the same letter(s) are not significantly different according to Duncan’s multiple range test at P ≤ 0.05. Potential reproduction index was calculated by dividing final population of a given cultivar on final population of the highest one multiplied by 100.Where 21–40.9% PRI = less susceptible (LS), 41–50% PRI = moderately susceptible (MS), and 51–100% PRI = highly susceptible (HS)
  3. Pf = final population, Pi = initial population
