Resumo: | Fourteen Acacia saligna provenance were evaluated based on the growth at 15 months of age in two sites of northern Chile. Type B genetic correlations were estimated to examine the genotype x environment interaction (G x E) of total height, mean canopy diameter and basal diameter. Restricted Maximum Likelihood (REML) method was used to calculate the variance components. Genetic correlation values were moderate (GpB = 0,46) to low (GpB = 0,27 y 0,17) in total height, and basal diameter and mean diameter of tree canopy, respectively, indicating high G x E interactions. There was significant difference between provenances in single-site studied (p ≤ 0,01). Provenance mean growth varied among the sites, showing greater potential towards south of the Region. Provenance specific groups selection for each site is necessary if G x E interaction continues in the future, since the best group for a specific site not always will maintain its superiority in the other. |

Correlaciones genéticas tipo B fueron estimadas para examinar la interacción genotipo x ambiente (G x A) del crecimiento en altura total, diámetro medio de copa y diámetro de cuello. Máxima Verosimilitud Restringida (REML), fue el método utilizado para la estimación de componentes de varianza. Para el crecimiento en altura, la correlación genética fue moderada (ΓpB = 0,46). Para diámetro de cuello y diámetro medio de copa, los valores de correlación genética mostraron un valor bajo (ΓpB = 0,27 y 0,17, respectivamente), indicando una alta interacción G x A. Los resultados mostraron diferencias significativas entre las procedencias, en cada sitio estudiado (p ≤ 0,01). El crecimiento promedio de las procedencias varió entre los distintos sitios, mostrando mayor potencial hacia el sur de la Región. De persistir una alta interacción GxA en el tiempo, se hace necesario seleccionar grupos de procedencias específicos para cada sitio, debido a que no siempre el mejor grupo para un sitio específico mantuvo su superioridad en el otro.Universidade Federal de Santa Maria2005-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/178610.5902/198050981786Ciência Florestal; Vol. 14 No. 1 (2004); 103-109Ciência Florestal; v. 14 n. 1 (2004); 103-1091980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1786/1052Pobrete, Freddy MoraRojas, Raúl Menesesinfo:eu-repo/semantics/openAccess2017-05-16T18:25:19Zoai:ojs.pkp.sfu.ca:article/1786Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-16T18:25:19Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
