Investigation of resistance specificity amongst fifteen wild Solanum species to a range of Globodera pallida and G. rostochiensis populations

Abstract

AbstractThe breadth of resistance to populations of the potato cyst nematodes, Globodera pallida and G. rostochiensis, which differed both in virulence level and country of origin, was investigated in 15 wild Solanum species. A range of responses to the populations was noted, with significant interactions observed between the potato genotypes and Globodera populations assayed. Of the 15 wild Solanum species, seven appeared to be potentially valuable sources of wide spectrum resistance with low multiplication rates with all populations recorded. The inclusion of these species into a potato breeding programme is justified by this study.
