| No | Name | Period | Host plant | Virus | Description | Origin | Mechanism | Durability | Determinism | Controlling genes/QTL | Cloned Gene | QTL or gene(s) | Location |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | Resistance to Potato virus M from Rm | 1998 and after | Solanum tuberosum | Potato virus M | Two new loci for resistance to potato virus M, Gm and Rm, have been mapped in potato. Rm was mapped to the short arm of chromosome XI, close to the marker loci GP250 and GP283, where a hotspot for monogenic and polygenic resistance to diverse pathogens is located in the potato and tomato. | Solanum megistacrolobum | Rm induce a hypersensitive response in potato plants. | Unknown | No | Rm | Chromosome XI | ||
| 2 | Resistance to Potato virus M from Gm | 1998 and after | Solanum tuberosum | Potato virus M | Two new loci for resistance to potato virus M, Gm and Rm, have been mapped in potato. Gm was mapped to a central region on potato chromosome IX. | Solanum gourlayi | Gm confers resistance to PVM infection after mechanical inoculation. | Unknown | No | Gm | Chromosome IX | ||
| 3 | Resistance to Potato leafroll virus from QTL | 1998 and after | Solanum tuberosum | Potato leaf roll virus | Quantitative trait locus (QTL) analysis of resistance to potato leafroll virus accumulation revealed one major and two minor QTL. | Resistance to PLRV is controlled by genetics factors that limit plant infection by viruliferous aphids or virus multiplication and accumulation. | Unknown | No | a major QTL PLRV.1 and two minor QTL | PLRV.1 on chromosome XI; the two minor QTL mapped to chromosome V and VI. | |||
| 4 | Resistance to Potato leafroll virus from PLRV.4 | 2004 - 2007 | Solanum tuberosum | Potato leaf roll virus | A novel locus for potato resistance to potato leafroll virus (PLRV) was characterized by inheritance studies and molecular mapping. The PLRV.4 locus was mapped to a central position on linkage group XI of the potato molecular map, where no resistance locus has been mapped previously. The inheritance of resistance to PLRV accumulation may be explained by a model of two complementary alleles of a single gene (PLRV.4) or by two complementary genes that are closely linked in repulsion phase. | Unknown | A model of two complementary alleles or a single gene (PLRV.4) | No | PLRV.4 | Chromosome XI | |||
| 5 | Extreme resistance to Potato virus Y (PVY) from Ry-fsto | 2004 - 2008 | Solanum tuberosum | Potato virus Y | A novel locus for extreme resistance to Potato virus Y (PVY), Ry-f>sto was identified on potato chromosome XII. Bulked segregant analysis identified an ISSR marker UBC857980 linked to Ry-fsto. This marker mapped to linkage group XII of a reference potato RFLP map. CAPS marker GP122718 converted from chromosome XII specific RFLP markers was tightly linked to the resistance gene. | Solanum stoloniferum | Unknown | a single dominant gene | No | Ry-fsto | Chromosome XII | ||
| 6 | Resistance to Potato virus S | 1998 and after | Solanum tuberosum | Potato virus S | The potato virus S resistance gene Ns maps to potato chromosome VIII. The dominant allele Ns confers in potato resistance to Potato virus S. To identify the chromosomal location of Ns, we mapped the Ns-linked marker SCG17448 and the ISSR marker UBC811600 to linkage group VIII of the RFLP map of a population that did not segregate for Ns. The genetic distance between Ns and the closest CP16 locus was 4.2cM. | Unknown | dominant allele | No | Ns | Chromosome VIII |
