Genetic factors encoding resistance to late blight caused by Phytophthora infestans (Mont.) de Bary on the potato genetic map

Late blight, a potato disease caused by Phytophthora infestans (Mont.) de Bary, is of great economic significance, and has been the subject of numerous research projects aimed at both introducing resistance to the disease into potato cultivars, and at unravelling the mechanisms and genes underlying this resistance. This report is on publications about mapping the resistance to P. infestans encoded by major resistance genes or polygenes, introduced into the potato from different sources. Applied methods for resistance evaluation, methods for revealing DNA polymorphisms and for the construction of genetic maps are described and compared, as are results obtained by independent authors working in this field.
