Abstract
Susceptibility of pome fruit genetic resources towards fire blight, caused by the bacterium Erwinia amylovora was evaluated with Swiss genetic resources.
The tests were performed in a security glasshouse using a shoot inoculation tests.
More than 200 different apple and pear genotypes were evaluated and revealed considerable differences in shoot susceptibility ranging from almost resistant to highly susceptible.
Based on the results, some accessions were included in the apple breeding program as fire blight tolerant parents.
Moreover, while considering also other agronomic and fruit quality characteristics, some accessions are currently recommended for fruit growing, especially on standards trees used for the production of apple juice and cider.
Those standard trees are additionally contributing to a diverse, ecologically desirable landscape.
