- Abstract
- Isolates of Tomato spotted wilt virus (TSWV) severely and systemically
infecting commercial pepper cultivars with resistance introgressed from
Capsicum chinense PI15225 were found in Albenga (NW Italy) in July 2000.
Experimentally, these resistance-breaking (RB) isolates overcame the
resistance in C. chinense PI152225, but they produced infection in other
hosts similarly to non-RB isolates from the same area. The RB isolates
were indistinguishable from TSWV by serology and electron microscopy and
they were efficiently transmitted by Frankliniella occidentalis. Such
isolates were recovered on the same farm in tomato, pepper and artichoke 2
and 12 months later, suggesting natural spread from the resistant plants
and survival. The RB isolates survived in experimental mixed infections
with a non-RB isolate in susceptible pepper and C. chinense, but cross
protection in pepper acted against them. Commercial TSWV-resistant pepper
but not resistant tomato cvs from different companies were susceptible to
these RB isolates after mechanical inoculation. Similar isolates were not
detected among TSWV samples collected from 1993 to 2000 in the area. The
management of TSWV and thrips using resistant pepper cvs is discussed. (literal)
