Two field isolates of tomato spotted wilt tospovirus overcome the hypersensitive response of a pepper (Capsicum annuum) hybrid with resistance introgressed from C. chinense PI152225
Plant Disease 83 (10), 965-965
Abstract: During 1998, pepper (Capsicum annuum) hybrid plants with resistance to tomato spotted wilt tospovirus (TSWV) and grown in Itally were observed with TSWV-like symptoms. More than 50% of the plants were diseased. The presence of TSWV was confirmed in the symptomatic plants using specific antisera and indicators plants. In pathogenicity tests the isolate could infect about half of Capsicum chinense plants which are regarded to be resistant to this virus.
