Conteúdo: 	Bacterial spot caused by Xanthomonas axonopodis pv. vesicatoria is considered one of the most destructive diseases in sweet pepper. Long rain periods, low resistance of the national cultivars, and inefficient chemical control favour infection and disease development. Inheritance of resistance to bacterial spot was investigated with P1, P2, F1, F2, BC1, and BC2 generations obtained from the cross Hercules (P1) x UENF 1381 (P2). All these generations (40 P1 plants, 40 P2 plants, 40 F1 hybrids, 268 F2 plants, 80 BC1 and 80 BC2 plants) were cultivated in a greenhouse. These plants were inoculated with isolate ENA 4135 (103 cells ml-1 1.0 cm-2 mesophile) to assess their reaction to bacterial spot. Broad- and narrow-sense heritabilities were 82.54 and 50.17%, respectively. The average dominance degree indicated presence of overdominance and at least three recessive genes control resistance inheritance.
