Multi-resistance as a source of differentiation in a varietal panel

symptoms of late blight on foliage
Screening for susceptibility to soft rot on tubers
Screening for susceptibility to soft rot on stems

Our final goal is to release genotypes that combine resistance to different pathogens. Projects include:

  • The use of molecular tools to characterize resistance loci or genotypes harboring resistance.
  • Assessment of resistances to new (emerging) pathogen strains or species

The use of molecular tools to characterize resistance loci or genotypes harboring resistance.

Molecular markers are already being used to detect certain resistance factors thanks to previous results obtained in French or European projects.

We specifically aim to characterize multi-resistant progenitors i.e.that combine resistance to:

  • PVY virus and Globodera pallida (Gpa) nematodes;
  • Foliage late blight and Gpa;
  • Meloidogyne incognita and Gpa nematodes.

We also intend to develop additional markers for Mh locus conferring resistance to Meloidogyne incognita and for Rysto gene conferring extreme resistance to PVY virus.

Assessment of resistances to new (emerging) pathogen strains or species

Populations of bacteria, pathogens that causeblack leg,as well as of Phytophthora infestans that cause late blight, are highly diversified.

We thus need to determine whether resistance factors to Pectobacterium atrosepticum in progenitors that have been provided to breeders by INRA since 1995, are also effective against the recently identified pectinolytic species Pectobacterium and Dickeya. We will also evaluate the sustainability of certain sources of resistance to late blight.

Genetic resistance to soft rot identified some years ago against is also efficient against new bacterial strains

Pectobacterium and Dickeya diversity studies have shown that a species/subspecies complex is responsible for soft-rot and blackleg. Can resistance...
