Description: Genotype-environment interaction (GEl) in beefcattle can be characterized by the change of the ser of genes which express a trair in function of the environment production. Genetic correlation between the trair studied in different environments measures the extent in which this change occurs. The aim of this study was to evaluate rhe existence of GEl on eighteen monrh weight (EMW) in Canchim cattle. through genetic correlations obtained by bayesian inference. Three different clusters of cicties in the State of São Paulo. homogeneous with respect to environment variables. were considered as the environments. The statistical model included the fixed effects of contemporary group and age at weighing (covariate). and additive and residual random effects. The heritability estimares ofEMW were low to moderare in magnitude [0.20-0.35] for rhe three clusters. The genetic cotrelations berween EMW in rhe rhree clusters varied from 0.13 to 0.34. suggesting rhe existence of GEl. The results showed rhat phenotypic expression of EMW depended on the environment in which it was measured.
