Research Project: Improved Breeding and Variety Evaluation Methods to Reduce Acrylamide Content and Increase Quality in Processed Potato Products

Location: Small Grains and Potato Germplasm Research

Project Number: 5366-21000-032-07
Project Type: Reimbursable

Start Date: Sep 01, 2011
End Date: Aug 31, 2014

Objective:
The goal of this proposal is to facilitate the rapid, efficient development and introduction of new potato varieties with lowered concentrations of acrylamide in their potato products following processing.

Approach:
The ARS potato breeding program at Aberdeen, Idaho will be a participating field site for the production and evaluation of breeding clones and varieties for: 1) the National Fry Processing Trial, 2) potato mapping populations to determine the genetic heritabilities of asparagine, tuber sugars, and acrylamide, and 3) identifying and validating SNP markers for their usefulness in marker-assisted selection for tuber sugar content. Participation also will include providing seed of material for evaluation for lowered acrylamide formation based on reduced tuber sugars and asparagine concentrations.
