Abstract
Resistance to Globodera pallida Rookmaker (Pa3), originating from wild species Solanum tarijense was identified by QTL analysis and can be largely ascribed to one major QTL. GpaXI tar l explained 81.3% of the phenotypic variance in the disease test. GpaXI tar l is mapped to the long arm of chromosome 11. Another minor QTL explained 5.3% of the phenotypic variance and mapped to the long arm of chromosome 9. Clones containing both QTL showed no lower cyst counts than clones with only GpaXI tar l . After Mendelising the phenotypic data, GpaXI tar l could be more precisely mapped near markers GP163 and FEN427, thus anchoring GpaXI tar l to a region with a known R-gene cluster containing virus and nematode resistance genes
