In the years 1999-2001, using two forecrops spring wheat and winter rape, crop yields of 6 wheat cultivars were compared in the conditions of the conventional (ploughed) tillage, simplified (ploughless) and direct seeding methods. On the basis of discriminant function analysis and analysis of concentration using the nearest neighbour method large variations in crop yields for the particular cultivars were revealed in relation to the 3 cultivation methods and 2 forecrops. The simplified tillage variants led to decreased crop yields. The greatest discriminating power for differentiating the examined genotypes was exhibited by the conventional (ploughed) soil cultivation on the two forecrops as well as the simplified method and direct seeding on the stand after spring wheat. Izolda and Kobra cultivars were marked by a higher average crop yield in the examined environments, compared to the other genotypes.
