The resistance responses present in 15 wild Solanum species to the potato cyst nematode Globodera pallida were investigated, focusing on hatch, invasion, development, sex determination and fecundity. A wide range of resistance responses was observed among the species, which impacted at different points in the life cycle of G. pallida. For most species a reduced rate of development and subsequent shifts towards an increased male to female ratio, indicative of a poor nutritional host, were observed. However, S. acaule ssp. acaule and S. canasense appeared to possess unique resistance responses, and may comprise valuable sources of new genes for incorporation into potato breeding programmes.
