"Two-dimensional resistance" as demonstrated by the interactions of potato cultivars Kennebec (A), and Maritta (B), with Phytophthora infestans. Both cultivars carry the hyper- sensitivity monogene Rl. This gene imparts complete, differen- tial resistance to the races 0, 2, 3 and 4, and to the complex race

This gene imparts complete, differen- tial resistance to the races 0, 2, 3 and 4, and to the complex races 2,3; 2,4; 3,4; and 2,34 of the pathogen. Kennebec also displays a low, and Maritta a medium level of uniform resis- tance (after van der Plank, 1963)..
