PCI’s Official Variety Attribution References

Under PCI’s new Variety Validation Service, we can only attribute those varieties included in the references listed here.  At certain times and at our discretion, we will attribute a variety not included in any of the listed references, and add that variety’s description and photographs on our web site.  In that way, everyone can have access to the source information for that attribution.
