Project Number: 6607-21000-009-01
Project Type: Specific C/A

Start Date: Sep 01, 2001
End Date: Aug 31, 2004

Objective:
The objective of this cooperative research project is to analyze 250-300 accessions of sweetpotato, presently being maintained in vitro, for molecular polymorphisms using amplified fragment length polymorphisms (AFLP's).

Approach:
About 250-300 unimproved sweetpotato clones consisting of wild species, numerous PI's and landraces collected over the years over a wide geographic range will be analyzed for AFLP polymorphisms. The AFLP polymorphisms will be analyzed phenetically to identify clones which are representative of the molecular diversity present in the sweetpotato germplams collection. Molecular marker data, geographic origin, and characterization and evaluation data will ultimately be used to select a set of 100-200 clones to serve as the core collection for this crop. The molecular markers will facilitate monitoring of genetic changes that may occur in the collection and for comparison with marker profiles of putative additions to the collection.
