Language: Polish

Keywords:

Summary:
In he paper, methods of breeding progress utilization in production are presented. Generally, in those methods, indices of yield creating value and linear regression analyses are applied. Survay data from 7867 fields of farms where winter wheat were cultivated during period 1986- 2002 were analyzed.
