PLEASE READ ALL INSTRUCTIONS CAREFULLY:
In the spaces on the left, enter the appropriate numbers that describe the characteristics of the application variety. 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. Please follow the guidelines on page 1 for conducting the trials. The comparison variety should be grown in field trials with the application variety for two independent growing cycles, at one or more localities, in the region and season of best adaptability. In general, measurements of quantitative traits should be taken on at least 24 randomly selected plants or plant parts to obtain averages and statistics that describe a typical field of the variety.
