Popis: Two strains and 8 isolates of PSTV in Rutgers tomato were successfully transmitted to all 87 Katahdin, Saco, and Irish Cobbler potato plants by grafting. Sap inoculation of these same varieties with the virus from tomato resulted in 66% transmission. Only 34% of the sap-inoculated Katahdin plants were infected as compared with 71% of Saco and 87% of Irish Cobbler. No differences in transmission could be attributed to the virus strains or isolates used. PSTV was detected in 14 of 16 infected potato plants in one test and in all 16 infected plants in another test with Rutgers tomato as an indicator plant. In a test of field-grown potato plants, PSTV was detected in 82% of 120 infected potato clones indexed on tomato.
