| Resumo: |
Records on 105 465 Nellore calves born from 1977 to 1994 in eight regions of Brazil were studied to evaluate the effects fo genotype x environment interaction on weaning weight calves. Teh interactions were estimated by the genetic correlation of weaning weight in defferent regions. To eastimate the variance and covariance components to obtain the genetic correlation of weaning weight under different regions, a sire model and MTDFREML solftware wereused for two regions each time. The matematical model included the fixed effects of year(17) and month(12),sex(2) of calf, farm(419) and age of dam (covarable), and the random effect of sire(588) and dam (57 162). The sire components of variance for each of the regions where 20.33,28.08,17.72,29.80,34.36, 38.08, 37.72 and 21.44. The phenotypic componrnt were 375.11, 430.65, 406.63, 408.99, 400.44, 412.71 and 335.74; for regions one two eight, respectively. T
