Adaptation of the Cyst Nematode Globodera pallida to the Colinear Potato Resistant QTLs GpaV_vrn and GpaV_spl Involved Distinct Genomic Regions and Absence of Cross-Virulence.

ABSTRACT: The use of alternative methods to control cyst nematode populations has accelerated since the ban of chemical nematicides in Europe. The resistant QTL GpaV_vrn, derived from the wild species Solanum vernei, is widely present in resistant European potato cultivars and provides strong protection against Globodera pallida populations although a risk of resistance breakdown has already been demonstrated in both experimental evolution studies and field populations. The wild relative S. sparsipilum, harbouring the resistant QTL GpaV_spl, would be an interesting alternative source of resistance to control virulent G. pallida. The goal of the present study was to understand the genomics of adaptation of the nematode to these two colinear resistant QTLs. Starting with two natura
