Genetic characterization of EB resistance
Tomato cultivars NC84173, NCEBR2 and NCEBR4
showed significant differences in the responses to EB
pathogen (Table 2): NC84173 had high susceptibility
while NCEBR2 and NCEBR4 lines had high levels of
resistance (P < 0.01). The results demonstrated that EB
resistance in NCEBR2 and NCEBR4 were quantitatively
controlled by more than one gene or QTL (Figure 1).
