About PVP Reg. Number:
      ---------------------
      Presence of a seven digit number in this category indicates the 
      cultivar has been submitted for certification by the Plant Cultivar
      Protection Office.  The Federal Plant Cultivar Protection Act of 1970
      (Public Law 91-577) permits exclusive rights of ownership and 
      distribution for developers of cultivars demonstrating unique
      characteristics.  The status of a particular application (e.g.
      pending, issued and enforced, abandoned or withdrawn) is also
      indicated.  The presented date represents the effective date of the
      most recent change in status of a particular certificate.  The number
      of PVP wheat cultivars compared to all wheat cultivars released in the
      United States during the last 3 decades are shown in figure 2 (sorry,
      gopher does not do graphics yet).  During the 1980's, approximately 50
      percent of all wheat cultivars were registered with the Plant Cultivar
      Protection Office.  Additional information on the Federal PVP Act of
      1970 and the status of protected wheat cultivars can be obtained from
      the Plant Cultivar Protection Office, USDA-Agricultural Marketing
