The Pinus tecunumanii species was introduced in the 1980s in the Central Rainforest of Peru, in the purpose of reducing the pressure on natural forests. At the moment the reforestations are carried out with the species because of its rapid growth, adaptability, plasticity and rusticity. The investigation was to characterize the quality of the Pinus tecunumanii propagated from local seed "Provenance 1” and seedlings propagated from imported seeds " Provenance 2 " at the forest nursery of the Universidad Nacional Agraria La Molina Annex Oxapampa - Central Rainforest of Peru, during the months of July to December 2019. The production process was carried out using the production standards of the university's forest nursery, 4 "x7 "x2mm polyethylene bags of 300 cc capacity were used (substrate of soil, sand, ground bark, ground needle and rice husk) the evaluation was for 22 weeks. The STUDENT t-test verified the existence of significant differences for height, diameter at neck height, total dry biomass, robustness index, ratio of aerial dry biomass to radicular dry biomass, lignification index and Dickson’s quality index; with respect to total humid biomass and radicular dry biomass there were no significant differences. The seedlings from Provenance 2 were found to have better averages for height, but both origins were classified as high-quality, with respect to diameter at neck height and robustness index the Provenance 1 registration a medium-quality and the Provenance 2 registration a low-quality, the best estimates for total humid biomass and total dry biomass were recorded at Provenance 1, with respect to the Dickson’s quality index, both provenances were classified as low-quality. Seedlings from Provenance 1 had superior morphological attributes and quality indicators during the nursery phase.
