| Description
| - Fire blight, caused by Erwinia amylovora, is an infectious disease affecting pome fruit and other members of the rose family. It is a serious concern to producers of apples and pears in the Czech Republic. Under optimal conditions, it can seriously damage an entire apple or pear orchard in a growing season. Resistance of old local pome fruit cultivars to E. amylovora was tested in an in vitro culture assay. Four pear cultivars (´Belle de Bois´, ´Jakubka ceska´, ´Doynne de Merode´, ´Solanka´) and two apple cultivars (´Boiken´, ´Nonnetit´) were selected for testing. A verified isolate of E. amylovora (Ea 8/95) isolated from necrotic tissues of hawthorn (Crataegus x monogyna) was used in tests. The apical tip of the shoot was removed with scissors and two concentrations of the pathogen (103 and 106 cfu/ml) were applied on the cut surface. Based on the results, ´Solanka´ was the most resistant and ´Doynne de Merode´ the most susceptible of the selected pear cultivars. Concerning apple, two cultivars ´Boiken´ and ´Nonnetit´ were tested. In this test, cultivar ´Boiken´ was three times more susceptible than ´Nonnetit´. ´Nonnetit´ showed minor symptoms of necrosis 9 days after inoculation. Preliminary results from inoculation of pear and apple shoot tips maintained in tissue culture with E. amylovora was a useful method to test fire blight resistance in pome fruit cultivars. The obtained results are preliminary and evaluation of additional cultivars will be carried out in following years
