Reforestadora del Sinú, Colombia branch, is a forestry company dedicated to the production and establishment of fast-growing timber species specifically “Eucalyptus grandis X Eucalyptus urophylla” on the Colombian Caribbean Coast with field operations in the departments of Córdoba and Antioquia. The objective of the internship was to select and propagate high-yield trees (plus trees) of the Eucalyptus hybrid (Eucalyptus grandis X Eucalyptus urophylla.) In plantations of the Reforestadora del Sinú Colombia branch. It was carried out in the seed stands of the company in the municipalities of Valencia Córdoba, Las Plata Antioquia, Turbo Antioquia and Montería Córdoba where the “La Ribera” nursery is established. The work consisted specifically of touring the seed farms within the municipalities where the seed trees were located, to make the selection it was based on the method of Zobel and Talbert, where they were selected individually taking into account the phenotypically desired parameters. In the seed collection, it was taken into account to climb the trees to the middle third of the tree where the branches that met the parameter were found, for the propagation and multiplication process, the different propagation techniques to be implemented in the plant were taken into account. Company: propagation by cuttings, grafting and induction of shoots. As a result, the selection of the trees plus mainly took into account the phenotypic characteristics such as the crown, angle of the branch, bifurcation, phytosanitary status and sociological position. It was obtained that the propagation by the three observed methods did not have a homogeneous behavior in the eucalyptus species, where we can highlight the staking method since it has a better behavior with respect to the other two methods. To conclude we have that Zobel and Talbert's method in the selection of plus trees of the eucalyptus species used in the company presented good results and it can be stated that despite being the same eucalyptus species (Eucalyptus grandis X Eucalyptus urophylla) and under the The same conditions do not have the same percentage of propagation, this can be attributed to the manipulation of the plant material and the skill of the graft.
