| Abstract: | An isolate ofVerticillum dahliae Vdp-4, pathogenic to both tomato and pepper (tomato-pepper pathotype), was examined for its vegetative compatibility with
testers of the Japanese vegetative compatibility group (subgroups J1, J2, and J3). Seven isolates ofV. dahliae from the same field as Vdp-4 in Misato, Nagano Pref. and two isolates from Hokkaido were separately determined as either
tomato pathotype (B) or pepper pathotype (C). Isolate 5922 previously reported as tomato-pepper pathotype was also examined.
Compatiblenit1 and NitM mutants were obtained from all isolates except for isolates Vdp-3 and Vdt-10. The isolate of tomato-pepper pathotype
Vdp-4 showed a strong reaction with VCGJ1 and J3 and was thus assigned to J3. Seven of these isolates showed compatibility
and were assigned into three provisional subgroups. The isolate 5922 was self-incompatible. |
