The easiest way to see all registered poly's with the registration percentage is using the AHS database advanced search and click on "Polymerous". This brings up all 280 registered polys.
You can also use the NGA database Search by Characteristics feature and find polys with images from the members and links to the AHS database registration info for each cultivar.
Another site I found several years ago has the registered polys listed by percentage with the highest to lowest, but appears to have not been updated in some time.
