The aim of this paper is to establish similarities or differences between water sorption characteristics of the most important Argentine wheat varieties and to propose a statistical methodology for their comparison. Ten varieties of wheat were studied by an isopiestic method at 25°C. A balanced two-way analysis of variance with interactions was used. The usual F-tests, assuming normality of the errors, and free-distribution tests were carried out. For the latter test specific software was developed. Transformations were eventually made in order to verify the underlying assumptions of the model. This methodology allows the grouping of 10 varieties according to nonsignificant differences.
