The present experimentation was developed with the objective of evaluating the emergence, vigor and pre-transplantation phenology of seedlings from seed sown with and without endocarp, of nine coffee genotypes in Oxapampa, in order to have new genotypes of uniform seedlings. An experimental design of randomized blocks with factorial arrangement was used. The experiment had two phases: i) in a germinator, seeds with and without endocarp were sown for each genotype, and ii) under nursery conditions, plants from sowing seeds with and without endocarp were pricked for each genotype. For the variables evaluated in the germinator and nursery, the genotypes that stood out were the following: UNACAF-89 (red caturra): emergency percentage (57%); growth rate (4,04 mm/week); UNACAF-116 (catimor): seedling fresh weight (0,64 g); seedling vigor index (53,79); aerial part fresh weight (2,36 g); root fresh weight (1,27 g); aerial part dry weight (0,53 g); root dry weight (0,16 g); root volume (1,25 ml); UNACAF-250 (obata): seedling dry weight (0,13 g); plant height (10,13 cm); UNACAF-188 (yellow caturra): emergence rate (1,17 plants/day) and UNACAF-213 (geisha): stem diameter (2,81 mm). In the group of seeds sown without endocarp, there were improvements for the variables: emergence percentage, emergence rate, seedling vigor index, root fresh weight and root volume. UNACAF-89 (red caturra) obtained the highest number of plants in secondary stages 09 and 10; likewise, the largest number of hypocotyls in the secondary stage 07 of the BBCH scale
