Table 2.
Solanum pinnatisectum and Solanum cardiophyllum show distinct patterns of the phenotype challenged by different isolates of Phytophthora infestans with a different ability to infect the differential set of potato carrying R1 to R11.

“-” refers to HR or no lesion; “+” refers to sporadic lesion; “++”refers lesion without sporulating; “+++” sporulating lesion; “+/-” refers to sporadic lesion was visible at least once in three biological repeats, otherwise no lesion was observed.
