  Soil samples from corky ringspot (CRS) problem fields of potato in the states of Washington and Oregon were collected and planted with Nicotiana tabacum 'Samsun NN' tobacco to bait tobacco rattle virus (TRV) and to increase Paratrichodorus allius populations, the vector of TRV. Pathogenicity of three isolates of TRV was assessed on Russet Burbank and Russet Norkotah plants using P. allius as the vector. The most severe CRS tuber symptoms were with TRV from Pasco, WA, followed by Umatilla, OR, and Mattawa, WA, indicating a distinct variation in virulence among virus isolates. The lowest number of P. allius that transmitted TRV resulting in CRS symptoms on Russet Norkotah mas three nematodes per 250 cm(3) soil. When potato plants mere exposed to P. allius at different times in their growth, tubers on older plants were more resistant than younger tubers to CRS. Severity of CRS tuber symptoms mas correlated with age of potato plants in pot culture. Reproduction of P. allius on potato roots did not influence the incidence and severity of tubers symptoms. Under similar conditions, Bintje, a variety known to be resistant to CRS, served as a host for P. allius, yet remained asymptomatic. The protocol employed in these studies is appropriate for testing potato germplasm for resistance to CRS.
