传统的甜椒品种表现出对马铃薯Y病毒（PVY）的敏感性，正在被具有更高商业价值的抗性杂交品种所取代。尽管有很多关于抗源反应及其遗传的信息，但对商业化抗源杂交种的遗传背景却知之甚少。甜椒（Capsicum annuum L.）评价马铃薯Y病毒（PVYm）的杂种，如Acuario、MagaliR、Nathalie及其各自的F2和F3代以及杂种阿曼达、Corteso W208、CPC-6272、Dagmar、Elisa、Magali、Margarita、Monteiro、Quantum、Vivo W205。将对PVYm的反应评价为抗性或敏感性。Magali R和Nathalie杂种没有表现出任何花叶症状。Magali R和Nathalie杂种的抗性是由于单显性基因指示抗感亲本系杂交系谱。抗PVY的阿曼达、Acuario、Corteso W208、Dagmar、Elisa、Margarita、Monteiro、Quantum和Vivo W205对PVY m.声称对胡椒斑驳病毒（PepMoV）具有抗性的杂交种也对PVYm具有抗性。
Traditional sweet pepper cultivars showing susceptibility to the Potato virus Y (PVY) are being replaced by resistant hybrids with higher commercial value. Despite 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 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.
