Abstract
This work presents the theoretical development of retrospective analysis methods, which are appropriate to study unbalanced historical data sets from multi-environmental series of experiments carried out for many years. These methods are the first part of pattern analysis methods and they are used for clustering locations in the way by which they discriminate among genotypes. The paper describes an idea of calculating proximities between locations and averaging proximity matrices over years. These procedures were used in the SEQRET package, which has been exemplified in Part II of the work.
