Project Number: 5442-43440-012-00
Start Date: Jul 02, 2010
End Date: Jul 01, 2015
To cooperate with potato breeders, producers, and processors to improve post harvest potato quality by reducing storage and processing losses. A major portion of this effort involves the evaluation of storage and processing characteristics of promising new varieties and advanced germplasm developed and submitted by U.S. potato breeding programs. Identify new genotypes with the ability to process directly from a storage temperature of less than 7 degree C. Identify optimum storage conditions for new cold-sweetening resistant germplasm. Identify new germplasm exhibiting enhanced vitamin C content.
The specific objectives are:
Objective 1: Determine the effects of postharvest storage on process quality and nutritional composition of advanced breeding lines in collaboration with public potato breeding programs. Sub-objective 1.1: Determine storage and processing characteristics of advanced breeding lines. Sub-objective 1.2: Screen advanced potato breeding lines for cold storage potential.
Objective 2: Determine the total antioxidant and ascorbic acid (vitamin C) contents of advanced breeding clones at harvest and during temperature-controlled storage.
This research project is a service project that provides standardized storage, processing and analysis of advanced breeding clones submitted by public potato breeding programs. All protocols, storage conditions, and analytical methods used have been standardized in accordance with current industry practices and are therefore invariant. Specific approaches include: 1) storage, processing and evaluation of new breeding lines, 2) determine cold storage potential of selected clones and cultivars, and 3) determine total antioxidant and vitamin C contents of advanced breeding clones at harvest and during storage.
