PVPO NUMBER

Please read all Instructions Carefully.
In the spaces on the left, enter the appropriate numbers that describe the characteristics of the application variety. Any other characteristics should be recorded in the
Comments Section, and continued in Exhibit D, to help establish uniqueness. On the right, enter the appropriate numbers that describe the characteristics of the most
similar comparison variety. Right justify whole numbers by adding leading zeros if necessary. The variety that you choose for comparison should be the most similar one in
terms of overall morphology, background and maturity. The comparison variety should be grown in field trials with the application variety for 2-3 years in the region and
season of best adaptability. At least one year of trials should be conducted within the United States of America. In general, measurements of quantitative traits should be
taken from one trial on 15-25 randomly selected plants or plant parts to obtain averages and statistics that describe a typical field of the variety. A second trial of the
same size would be needed to establish distinctness based on quantitative data. (Form technical content last updated July 2008.)
