Incidence of onion yellow dwarf virus (OYDV) and leek yellow stripe virus (LYMV) on garlic

Abstract

During 2009, a total of 27 fall garlic cultivars were evaluated for Onion yellow dwarf virus - OYDV and Leek yellow stripe virus - LYSV disease intensity. The presence of virus was confirmed with DAS-ELISA test. Out of 270 tested samples, 60.4% proved to be infected with at least one of viral species. OYDV was found in 60.0%, and LYSV in 3.0% of analyzed plants. In 2.6% of samples mixed contamination with both viruses was determined. Percent of infection of tested garlic cultivars varied from 0 to 100% with OYDV and 0-30% with LYSV.

Tokom 2009. godine utvrđen je intenzitet zaraze 27 genotipova jesenjeg belog luka virusima žute patuljavosti crnog luka (Onion yellow dwarf virus - OYDV) i žute prugavosti praziluka (Leek yellow stripe virus - LYSV). Prisustvo virusa dokazano je pomoću DAS -ELISA testa. Od 270 testiranih uzoraka u 60,4% je utvrđena zaraza sa bar jednim od dva ispitivana virusa. OYDV je bio utvrđen u 60,0%, a LYSV u 3,0% analiziranih biljaka. U 2,6 % uzoraka utvrđena je mešovita zaraza sa oba virusa. Zaraženost ispitivanih genotipova jesenjeg belog luka sa OYDV se kretala u granicama 0-100%, a sa LYSV 0-30%.
