Weaning weight, preweaning daily gain and 205-day weight of Hungarian Fleckviehcalves (n=8 929, bulls =4 539, heifers =4 390) born from 232 sires between 1980 and 2003were examined. Variance, covariance components and heritability values and correlationcoefficients were estimated. The effect of the maternal permanent environment ongenetic parameters and breeding values were examined. Two animal models were usedfor breeding value estimation. The direct heritability (hd2) of weaning weight, preweaningdaily gain and 205-day weight was between 0.37 and 0.42. The maternal heritability (hm2)of these traits was 0.06 and 0.07. The direct-maternal correlations (rdm) were medium andnegative −0.52 and −0.74. Contribution of the maternal heritability and maternal permanentenvironment to phenotype is smaller than that of direct heritabilities (hm2+c2< hd2). Theratio of the variance of maternal permanent environment in the phenotypic variance (c2)changed from 3 to 6 %. Estimated breeding values changed whether the permanentenvironmental effect of dam wasn’t taken into consideration but the rank of the animalswas not modified. The genetic value for weaning results of Hungarian Fleckviehpopulation has increased since 1997
