| Popis: | International audience; Fire blight, a devastating disease of apple, pear, and many Rosaceae species worldwide is caused by enterobacterium Erwinia amylovora. At present, disease control mainly relies on antibiotics, prevention, and eradication-based strategies. Prevention and eradication is expensive, while resistance development for antibiotics can reduce their efficacy over time. Apple varieties do, however, exhibit a wide range of relative tolerance to fire blight. As part of our long-term strategy to design sustainable fire blight controls, we have initiated a breeding project to identify quantitative trait loci (QTLs) and markers linked to them. F1 segregating progeny plants of 'Fiesta' * 'Discovery' were inoculated with a strain of Erwinia amylovora and studied under quarantine conditions to identify QTLs (Quantitative Trait Loci) for fire blight resistance. Progress of disease was measured at different time intervals as percent shoot lesion length (PLL) and used for QTL analysis. One significant QTL (P |
