Resumo: 	The study aimed to estimate parameters, values and genetic gain for growth traits in progenies of Eucalyptus camaldulensis, in the State of Mato Grosso. The progenies test was conducted under a randomized block design with 132 progenies, five replications and three plants in single rows, spaced 3 m x 2 m in Santo Antonio do Leverger, MT. At 24 months of age, progenies were evaluated for the characters: a) diameter at base height (DBH), in centimeters, b) total height, in meters, c) survival. The individual in the narrow sense heritability for the traits studied can be considered medium to high magnitude (0.13 and 0.21) for height and diameter, respectively. The heritability for survival were practically nil, due to low genetic variability among the progenies, as evidenced by high survival rate of the plants (96.8%). The phenotypic and genetic correlations were of high magnitude for DBH and height prediction. There is genetic variation among progenies for growth traits which will provide significant genetic gains with selection.doi: 10.4336/2012.pfb.32.70.49
