“…The Sw-5 gene that confers resistance to Tospovirus serogroups I (i.e., tomato spotted wilt virus, TSWV) and II (i.e., groundnut ringspot virus, GRSV, and tomato chlorotic spot virus, TCSV), derived from Lycopersicon peruvianum, was transferred to the cultivated tomato (Stevens 1964). The Tsw resistance gene to Tospovirus serogroup I (Black et al 1991;Boiteux 1995) originates from Capsicum chinense and is presently being introgressed into pepper cultivars (Costa et al 1995). At least five different C. chinense lines possess a single dominant gene at the Tsw locus conferring a hypersensitive resistance to TSWV: 'PI 152225', 'PI 159236', 'CNPH 275' (Boiteux 1995), 'C00943' (Black et al 1996), and '7204' (Moury et al 1997).…”

The hypersensitive resistance to tomato spotted wilt virus (TSWV) in pepper is determined by a single dominant gene (resistant allele: Tsw) in several Capsicum chinense genotypes. In order to facilitate the selection for this resistance, four RAPD (among 250 10-mer primers tested) were found linked to the Tsw locus using the bulked segregant analysis and 153 F 2 individuals. A close RAPD marker was converted into a codominant cleaved amplified polymorphic sequence (CAPS) using specific PCR primers and restriction enzymes. This CAPS marker is tightly linked to Tsw (0.9 ± 0.6 cM) and is helpful for marker-assisted selection in a wide range of genetic intercrosses.

The resistant reaction, which is identified in C. chinense accessions, PI 152225 and PI 159236, and controlled by a single dominant gene Tsw, can be induced by mechanical inoculation of TSWV (Boiteux and de Á vila 1994;Black et al 1996).…”

Considerable losses in pepper production by Tomato spotted wilt virus (TSWV) have been reported worldwide. In breeding programs, an assay for resistance that accurately estimates field occurrence of TSWV during pepper production is critical because the virus is vector transmitted. Here, we establish an assay system of TSWVresistant Capsicum spp. using insect-mediated inoculation within an acrylic chamber in which environmental conditions such as temperature, light intensity, and nutrient supply are controlled. This chamber enables transmission of TSWV from viruliferous plants to plants used in the resistance assay with Frankliniella occidentalis safely, quickly, and precisely.
