Table 3 Response types of T1 and T2 positive plants at V1–V4 stage

^aHR high resistance, indicating that no any visible symptoms appeared on the observed leaves
^bMR delayed resistance, indicating that symptoms could be observed at V₁ and V₂ stage, but not at V₃ and V₄ stage
^cDR mild resistance, indicating that the symptoms appearing on the observed leaves were lighter than the symptoms of susceptible plants
^dS susceptible, indicating the symptoms were obvious and severe, which were similar to negative control
