Additional notes about the collection

Worth pointing out are 8 clones which were selected for production in replicated experiments here in Puerto Rico and are included in the collection.  Also, we have some wild germplasm (pentagonum type), white beaned Criollo clones and a Nacional hybrid.  Several local highly productive farmer selections will become available in a year or so.
