Project Objectives
​
-
Unify terminology and develop quality control standards for Clean Foundation Seed
-
Develop best practices for efficient Clean Foundation Seed production in both the laboratory and greenhouse
-
Develop new technological innovations to determine the presence of viruses on-site and determine best practices that minimize their source and reinfection rate
-
Conduct economic analysis and launch CleanSEED marketing campaign to increase awareness and adoption of Clean Foundation Seed
CleanSEED Project
CleanSEED refers to foundation seed roots or plants produced from virus-tested plant material in a laboratory and sourced from a National Clean Plant Center (G0 plant material).
CleanSEED has been tested and found to be free of the following:

Sweetpotato feathery mottle virus (SPFMV)
-
Sweetpotato Virus C (SPVC)
-
Sweetpotato Virus G (SPVG)
-
Sweetpotato Virus 2 (SPV2)
