GpaXI(tar)(l) originating from Solanum tarijense is a major resistance locus to Globodera pallida and is localised on chromosome 11 of potato

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 chr...

Sumario: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.
