Descrição: The results of reliability in draught, which are part of the performance tests, were evaluated in both the warm- and cold-blooded stallions. The relationships between the separate repeated pulls evaluated on the basis of single, multiple and partial correlations (rxy, rx.yz and rxy.z, respectively), are highly significant. The author evaluates the differences in these relationships in performance tests on the separate stud farms and after concentrating the stallions for performance tests in one centre. The correlation coefficients were subjected to tests to verify their homogeneity. On the other hand, homogeneity of the correlation coefficients was not confirmed in the horses tested in the individual herds. No significant changes in the ranks of the horses were observed when the horses' point rating ranks were evaluated, using the non-parametric rank test of concordance. The current results are intended to serve as starting material for comparison with the results to be obtained in the newly built testing facility.
