Research Project: Understanding Bruise Related Issues in Potato Tuber During Long-Term Storage

Location: Sugarbeet and Potato Research

Project Number: 3060-43440-013-09-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: May 16, 2018
End Date: Jun 1, 2022

Objective:
Testing advanced potato selections or newly released potato cultivars for pressure bruise susceptibility and develop/test tools to determine tuber susceptibility to pressure flattening and associated bruising.

Approach:
Advanced breeding lines and selected potato cultivars representing fresh and processing markets will be grown in San Luis Valley, CO and at an irrigated field trial in Larimore, ND. After harvest a penetrometer will be used to assess tuber turgidity and skin set. Pressure flattening/bruising will be assessed after six months storage in replicated ventilated storage cabinets. The penetrometer predictive bruising score will be compared with the six month ratings. Data collection will include shrink, pressure flattening, internal bruise, and storage conditions. For select chip clones stored at East Grand Forks, MN, a chip merit score rating will be measured after six months of storage following processing through a continuous chip line.
