Virulence of Globodera pallida populations in the Netherlands

Populations of Globodera pallida (EPPO A2 quarantine pest) were collected from 392 infected fields in the north-eastern part of The Netherlands and were subjected to a variety test in order to analyze the resistance of the 7 starch potato cvs. used in the Netherlands. It was found that 33 populations expressed a relatively high virulence to all cvs. and especially to the cvs. "Producent", "Elles" and "Darwina". The authors feared that the selection pressure of these cvs. on G. pallida populations will push the nematode populations to similar virulence properties.
