Potato psyllid resistance may contribute to a reduced incidence of zebra chip disease.
Technical Abstract: A haploid tuberosum x Solanum berthaultii hybrid clone and its progeny from backcrossing to cultivated potato were screened for resistance to adult potato psyllid, the insect vector of Candidatus Liberibacter solanacearum (syn. Ca. L. psyllaurous) which is associated with zebra chip (ZC) disease. Potato breeding clones with the potato species S. raphanifolium, S. chacoense, and S. berthaultii in their pedigree were also screened for resistance to potato psyllid. Antibiosis and antixenosis to potato psyllid was displayed among breeding clones, which may aid in reducing transmission of the bacterium responsible for ZC.
