First report of Onion yellow dwarf virus in leek (Allium ampeloprasum var. porrum) in Spain.
In the spring of 2015, a total of 30 leek plants of 4 different cultivars (Curling, Custeau, Megaton and Pluston) showing symptoms of inverted roots and cracked stems, were collected from fields near San Pablo de la Moraleja, Valladolid (Castilla y León, Spain). The presence of Onion yellow dwarf virus (OYDV) was detected on the analysed samples based on various molecular analyses. This is thought to be the first report of the detection of OYDV in leeks from Spain.
