Abstract
A common evaluation system for filberts has been developed by research leaders of breeding programs in U. S., France, Italy, and Spain. The system incorporates important horticultural or economic traits and is independent of specific breeding objectives. To minimize the influence of site and season on certain traits, especially phenological traits, a standard set of well-known cultivars was established, against which all other clones are compared. Ratings are recorded numerically so the data can be readily computerized.
