Summary:
The ten varieties of winter wheat growing at different level of nitrogen fertilization have been investigated. The grain and flour eleven traits have been estimated. The data have been evaluated by means of the following statistical methods: multiple regression, Ward’s procedure of agglomeration in cluster analysis and factor analysis. Significant dependence of valorimeter value of wheat on linear combination of five other traits has been obtained. Three clusters of wheat varieties have been separated. Primary variables have been reduced to three dimensions, which explained about 80% of general variation.
