Traditional sweet pepper cultivars showing southwestern aztec rug susceptibility to the Potato virus Y (PVY) are being replaced by resistant hybrids with higher commercial value.Despite of much information about resistance source reaction and their inheritance, there is no knowledge about the genetic background of commercial resistant hybrids.Reaction of sweet pepper (Capsicum annuum L.

) hybrids to the Potato virus Y (PVYm) such as Acuario, Magali R, Nathalie and their respective generations F2 and F3 as well as hybrids Amanda, Corteso W208, CPC-6272, Dagmar, Elisa, Magali, Margarita, Monteiro, Quantum, Vivo W205 was evaluated.Reaction to read more PVYm was evaluated as resistant or susceptible.Magali R and Nathalie hybrid did not show any mosaic symptoms.

Magali R and Nathalie hybrids resistance is due to a single dominant gene indicating resistant versus susceptible parental lines crossing pedigree.Amanda, Acuario, Corteso W208, Dagmar, Elisa, Margarita, Monteiro, Quantum and Vivo W205, considered resistant to PVY, were highly susceptibility to PVY strain m.Hybrids, claimed as resistant to the Pepper mottle virus (PepMoV), were also resistant to PVYm.
