Abstract
This work presents the example of using pattern analysis methods, which are appropriate to cluster locations for unbalanced historical data sets from multienvironmental series of experiments with winter wheat carried out for many years. The SEQRET package was used for clustering locations in the way by which they discriminate among genotypes, and for calculating determination coefficients for years. The paper presents the use of procedures described in a theoretical Part I in practice.
