| Popis: | International audience; Both race-specific (RS) and race-non-specific (RNS) resistances exist in potato against the late blight pathogen Phytophthora infestans. Because these resistance types do not have the same epidemiological effects, their presence, alone or combined, in potato genotypes can be deduced from the analysis of disease progress curves from field experiments, a type of data commonly available to potato breeders, and their comparison with those of standard reference cultivars. The identification of RS resistance is based on the presence of a delay in epidemic onset compared to a susceptible cultivar, whereas the identification of RNS resistance is translated into a reduction of apparent infection rates. These parameters can be easily computed after linearization of the disease progress curves. This paper assesses the reliability of this identification using sets of experimental data, discusses its limitations, and highlights potential applications for breeding and cultivar assessment purposes |
