Resumo: | Abstract Tree breeders use traits of economic interest as productivity, stem form and wood quality, to select individuals for advanced generations. We determined the genetic control of growth volume, tree height and diameter, stem form and wood resistance, and calculated a selection index for Pinus maximinoi and P. tecunumanii, selected individuals were used to establish a seedling seed orchard (SSO). The largest genetic gain obtained in SSO for P. maximinoi was 21.48% for volume, while for P. tecunumanii it was 21.87% for stem form. There is enough genetic variability for genetic gain in future generations in tests of P. maximinoi and P. tecunumanii progenies. The selection index provided satisfactory total genetic gains for several traits, being more recommended than the BLUP method in order to support the selection and ranking of superior genetic materials in the progeny tests with greater probability of retaining favorable alleles over generations. |
