The potato is susceptible to a large number of pathogens, and varieties must respond to the need to reduce the use of phytosanitary products. Production also has to cope with the increasingly frequent and intense climatic hazards caused by global warming. The development of resistant varieties with all the characteristics required by users is therefore a major challenge for breeding.

Marker Assisted Selection (MAS) and genomic selection (quantitative traits) can help breeders meet this challenge by facilitating the identification of genotypes that carry genetic resistance.
