摘要:
SummaryWestern Australia has a unique seed potato production scheme which has remained virtually unchanged for more than 60 years, consisting of summer plantings of predominantly one cultivar in wind‐exposed coastal swamplands. No rotation is used and the scheme relies on natural winter flooding and ‘grazing’ by sheep to eliminate unharvested tubers. Stocks are recycled every year with only limited inputs of pathogen‐tested seed tubers in recent times. Virus spread in the crop is controlled by selecting large tubers for planting, roguing, aphicide application and growing season inspections. Potato viruses X and S were commonly detected in old seed stocks produced by this scheme attaining 100% infection in some. Both viruses were less frequently found in newly introduced seed stocks. By contrast, potato virus Y was never detected and potato leaf roll virus rarel
