Herbaceous test plants for the detection of quarantine viruses of potato
EPPO Bulletin 30 (3-4), 463-467
Abstract: To prevent the introduction and spread of non-indigenous potato viruses in the European Union, the import of potato breeding material is regulated by a Directive prescribing post-entry testing under quarantine. This testing includes serological screening and mechanical inoculation to herbaceous test plants. A list of appropriate test-plant species was published by EPPO in 1984, but some other promising test-plant species have been described since. This paper reports the reactions of nine plant species to six non-European potato viruses, including all the seed-borne viruses. Different isolates of all these viruses were detected on Nicotiana hesperis-67A as well as on N. occidentalis Pl. This means that all relevant viruses are detected if one of these indicators is used to test plants grown from true potato seed. The inoculation experiments will be continued with potato viruses that already occur in Europe. The results so far provide a good basis for improving the use of test plants in post-entry quarantine testing.
