Project Name |
Apple fire blight resistance trait-Peil-2014 |
Crop |
Apple |
Project type |
QTL |
Description |
Whereas most apple cultivars are susceptible to fire blight, several wild apple species accessions like Malus x robusta 5 (Mr5) bear significant resistance.QTL mapping was performed after inoculation of the population 04208 (Idared x Mr5) using strains differing in their virulence to Mr5. QTL mapping was performed after inoculation of the population 04208 (Idared 9 Mr5) using strains differing in their virulence to Mr5. The QTL mapping approach demonstrated that the major QTL on linkage group 3
could be confirmed after inoculation with strains nonvirulent to Mr5. In contrast, the major QTL disappeared after inoculation with strains virulent toMr5. Only after
inoculation with the resistance breaking strain Ea 3049 was a minor QTL with a LOD>3 found on linkage group 3. Additionally, several minor QTLs were
detected on linkage groups 5, 7, 11 and 14 of Mr5 after inoculation with virulent strains able to overcome the major resistance QTL of Mr5. |
