Various solutions for the analysis of the interaction variety x locality in a series of experiments are presented. A method is proposed which is equivalent to the cited procedures in the literature in this subject; based on orthogonal contrasts obtained from totals for each variety and locality.
The methods described were applied to an experiment in Potato which included 12 varieties and 4 localities.
A procedure is proposed for combining the observed means throughout all the localities and the components of interaction to adjust the observed means according to their higher or lower consistency.
