Research Project: Genetic Enhancement of Potatoes for Nutritional and Processing Quality and for Resistance to Diseases Project Number: 1245-21000-271-00
Project Type: Appropriated

Start Date: Mar 11, 2013
End Date: Jun 30, 2013

Objective:
Improve levels of disease resistance to foliar and soil-borne pathogens in potatoes Improve processing and nutritional quality in potatoes through breeding and selection of superior germplasm. Evaluate advanced selections through replicated field trials prior to naming and release to stakeholders.

Approach:
Use recurrent selection to improve diploid populations for disease resistances and processing quality. Use parental line breeding to improve tetraploid populations for disease resistances, processing quality, nutritional quality. Transfer these traits from improved diploids to the tetraploid level via 4x-2x crosses. Develop markers to facilitate introgression of desirable genes or deletion of undesirable genes from related species into commercial germplasm.
