The main aim of the study was to evaluate bread-making quality parameters in a set of five Czech and Slovak model varieties under conditions favourable for bread wheat production of high quality during a five-year period. A mean square ratio suggests a dominant effect of the year on bulk density, protein content and grain hardness. A positive correlation between protein and wet gluten content and nitrogen rates was found. However, besides nitrogen applied as pure nutrients, nitrogen from soil reserves affected protein synthesis in grain. Another factor affecting protein synthesis and accumulation in grain is a transport of nitrogen nutrients through a stem. This fact is supported by a very highly positive, highly significant correlation among rates of potassium nutrients and protein and wet gluten content in grain.
