dc.description.abstractThe aim of this study was to quantify the genetic variances among provenances and progenies of Pinus caribaea var. hondurensis to increase the wood productivity in northwestern of Paraná State, Brazil. The trial was established with seed from Guatemala and Honduras, in a randomized complete block design (57 progenies and four controls), nine replications and six plants per plot, planted in a 3 x 3 m spacing. The measured traits were: total height (H), diameter at breast height (DBH) and cylindrical stem volume (VOL). These traits were measured five years after planting. Variation pattern and genetic variation among and within provenances and progenies were estimated by using deviance analyses. Variance components and genetic parameters were performed by using REML/BLUP method. Mean ALT, DBH, and VOL were 8.81 m, 13.72 cm, and 0.09 m3.tree-1, respectively, with significant genetic variation among provenances and progenies. Estimates of individual additive genetic variation ranged from 5.5 % to 13.8% and the genotypic variation among progenies from 2.8 % to 6.9 %, indicating genetic variability. Individual heritability estimates varied from 0.06 to 0.51 in DBH and H, respectively. Genetic variations were high, mostly at family level and were highest among Guatemalan provenances. Provenances Lanquin and Las Trincheras, Guatemala, showed the largest wooden productivity perspective for studied site.en
