a
Disease incidence (DI) of diseased plants were assessed at 5 weeks after inoculation, calculated as DI = 100 × number of disease plants/ total number inoculated plants of each plot experiment (30).
b
Resistance reaction (RR) of 21 cultivars to strain RS378 was evaluated based on DI, where HR, highly resistant; R, resistant; MR, moderately resistant; S, susceptible; and HS, highly susceptible.
