Research Project: Assessing Tolerance of Zebra Chip Disease in Potato Varieties with Low Reducing Sugar Content

Location: Fruit and Vegetable Insect Research

Project Number: 5352-22000-020-13
Project Type: Trust

Start Date: May 01, 2013
End Date: Apr 30, 2015

Objective:
Assess the ability of potato varieties with low reducing sugar content to tolerate ZC disease and to reduce the amount of post-fry darkening observed in ZC-infected tubers.

Approach:
Conduct controlled insect exposure experiments under field cage conditions in WA to: 1) assess the ability of potato varieties with low reducing sugar content to tolerate ZC disease and to reduce the amount of post-fry darkening observed in ZC-infected tubers; 2) use potato lines with low sugar content developed by Simplot through the invertase silencing technique to salvage mildly ZC-infected tubers and make them usable, especially following late season Lso-infection; and 3) assess whether these potato lines produced through invertase silencing can minimize ZC development during storage.
