Means followed by the same letter in the columns do not differ (Duncan’s multiple range test, 5% probability), * Susceptible standard genotype; ** Moura and Régis (1987) scale of categorizing host resistances (in this classification, the genotype with the highest RF is used as the susceptible standard, then this genotype is compared with each of the others and the reduction percentage of the reproduction factor-RPRF- is calculated); {HS= highly susceptible (0 to 25% RPRF), S= susceptible (26 to 50% RPRF), LR= low resistant (51 to 75% RPRF), MR=moderately resistant (76 to 95% RPRF), R= resistant (96 to 99% RPRF) or HR=highly resistant (100% RPRF)}.
