Inbred and outbred Eucalyptus clone were assessed aiming to check the possible loss of vigor in the initial germination phases and growing in nursery and in t field conditions. Offsprings from two commercial clones were assessed as inbreds (C01 and C02) and as hybrids (C01 x C03 and C02 x C03). The work consisted of two phases. The first one was in the nursery, in a completely random design, with 4 treatments and 6 reps, in plots with 30 tubes with only one seed. The second one, in the field, used a randomized complete block design, with 4 treatments and 6 reps, with 18 plants per plots. The percentage of germination, germination speed index, survival and plant height were assessed at 35, 50, 65 and 80 days in the nursery and, in the field, the percentage of survival with 6 months and plant height with 2, 4 and 6 months. It was concluded that the germination, survival and the growing of plants resulted from inbred were similar to the hybrid, showing that the loss of vigor is not expressive for those characters in initial developmental phases of Eucalyptus spp.
