Conteúdo: 	Inheritance studies were conducted to determine the genetic basis of resistance in pepper against one Tospovirus isolate classifie as tomato spotted wilt virus (TSWV). F1, backcrosses and F2 populations were develop using the resistant parent Capsicum chinense 'PI 159236' (CNPH 679) and the susceptible parent C. annuum 'Magda' (CNPH 192). Segregation ratios strongly indicated that the resistant response (a localization, hypersensitive-like reaction) to TSWV fits a single-dominant gene model. Under our experimental conditions, the penetrance of this gene was very high. This gene (tentatively named Tsw) is highly effective only against TSWV isolates. The resistance governed by the Tsw gene was not effective against isolates belonging to tomato chlorotic spotvirus (TCSV) and groundnut ring spot virus (GRSV), two other previously described Tospovirus species.
