On a large number of trial and demo fields in all starch-counting countries, our varieties and new numbers are compared with the existing standard varieties. New numbers are only ranked by us if they have sufficient potential for the relevant growing regions. Any resistances of the numbers are determined by container examinations at renowned laboratories.
