Research Project: Utilizing Inbred Potato Clones to Determine Key Molecular Mechanisms Regulating Tuber Dormancy

Location: Potato, Pulse and Small Grains Quality Research

Project Number: 3060-21430-009-030-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2025
End Date: Aug 31, 2027

Objective:
The objectives of this project are: a) to monitor tuber dormancy characteristics of the inbred parental lines during long-term storage; b) to determine the molecular and biochemical changes in tuber tissues of the inbred lines during storage, and identify the genetic basis of tuber dormancy trait.

Approach:
Experiments will be conducted in a multi-institutional research setting, and the cooperator will perform the following: a) generate an F2 mapping population segregating for tuber dormancy trait; b) collect leaf samples for DNA extraction and SNP genotyping; c) perform linkage mapping and QTL analyses; d) provide tuber samples to ARS PI for postharvest storage analyses.
