Potato germplasm poses the highest risk of introducing Potato spindle tuber viroid in potatoes in the Netherlands: analysis and evaluation of an outbreak in potato breeding
European Journal of Plant Pathology 151 (1), 201-211
Abstract: In 2014, potato spindle tuber viroid (PSTVd) was identified in a potato clone originating from a breeding company in the Netherlands. This clone was submitted for micro propagation and therefore tested for PSTVd and a number of other pathogens. This finding of PSTVd initiated actions to track and eradicate the infections. In addition to the finding at the breeding company, PSTVd was also found at a research institute. At both locations the viroid was eradicated following extended testing and discarding of infected plants. Additional surveys including testing of each individual plant in all crossing glasshouses and random samples of pre-basic and basic seed potatoes, revealed no further infections in the Netherlands. This result concurred with the fact that mechanical spread of PSTVd in the field is not likely under climatic conditions in the Netherlands. Therefore, vegetative propagation seems the most important pathway for maintaining and spreading of PSTVd. Based on the evaluation of this outbreak, it was concluded that potato germplasm poses the highest risk of introducing this viroid in potatoes in the Netherlands.
