Abstract
Many new high yielding wheat varieties with good grain quality appeared recently on the Polish market. The effects of wheat breeding and their practical utilization were estimated. The estimation was conducted by the method of yield potential changing of varieties. As an effect of breeding, the average yield of wheat increased by 41 kg/ha per year, in the conditions of varietal tests carried out during the period of 1986–2001. Practical utilization of the plant breeding effects was lower. One of the main reasons of unsatisfied breeding influence on production was increasing dissonance between breeding effects and low seed supply of new varieties resulting from the lack of demand for seeds.
