Figure 2. Inoculation of detached leaflets with selected P. infestans isolates.

Figure 2

Detached leaflets were inoculated with P. infestans by placing a 10 µl drop of inoculum at 6 spots on the abaxial surface the leaflets. Photos were taken 5 days after inoculation. Average lesion (necrosis+chlorosis) diameters (in millimeters) of 24 replications are shown in Table 3. Top row: susceptible S. tuberosum cv. ‘Katahdin’; bottom row: transgenic ‘Katahdin’ containing the RB gene.
