Goals / Objectives
Potato breeding germplasm with known resistance to potato psyllid, insect vector of Zebra Chip, (ZC) and putative resistance to the bacterium responsible for ZC will be characterized to assess their individual and combined contribution to ZC resistance. In addition, Solanum-species derived potato germplam, not previously assayed for response to vector or pathogen, will be evaluated to identify new sources of resistance to ZC.
Project Methods
Potato psyllid behavioral bioassays and Candidatus Liberibacter solanacearum (Lso) transmission assays will be conducted on four breeding clones derived from etuberosum-berthaultii, the two PALB03016 clones, and the susceptible control, ¿Atlantic¿. Real-time PCR of Lso will also be conducted to allow quantification of bacterial titer in the foliage and tubers of breeding clones relative to the susceptible control to provide an assessment of relative resistance.
