Abstract
The paper attempts to characterize locations taking part in the pre-registration trials with winter wheat in the years 1999–2001. The following parameters were taken into account: average yield of genotypes, coefficient of variation of genotypic means, correlation coefficient of genotypic means with the marginal means from all experiments and the contribution of the environment to the total interaction. Large variability of the computed characteristics over different series of experiments (years) is shown. This variability causes difficulties in a simple classification of locations with respect to their value for genotype testing.
