A total of 23 isolates were obtained from seeds of 30 pepper cultivars by single lesion isolation on Nicotiana glutinosa. The isolates were tested for pathotype determination using standard pepper differentials. Two pathotypes of Tobamoviruses, namely P0 and P1.2 were detected from the pepper seeds, of which pathotype P1.2 was predominant. Pathotypes P1 and P1.2.3 were unable to detect in this study. All pepper cultivars except one showed resistance to two pathotypes, P0 and P1, but not to pathotype P1.2. These results could be useful for breeding Tobamovirus-resistant pepper and producing virus-free seed stock.
