Abstract

International efforts to explore genetic resources of Gmelina arborea Linn., Roxb. (gmelina) were formulated during the period 1969–1974 by the FAO Panel of Experts on Forest Genetic Resources. As a first step in the work in 1975, the Danish/FAO Forest Tree Seed Centre (later Danida Forest Seed Centre) initiated, together with a number of public and private organizations in more than 20 countries, an international provenance experiment. The experiment included 36 provenances of natural populations in India and Thailand together with 24 landraces from 20 countries. The provenances were included in 60 provenance trials, which were established in the mid-1970s by more than 20 host countries. The following paper gives a summary of the performance of provenances from different regions of India, Thailand, and from exotic plantations in various countries. The results show (1) that plants originating from exotic plantations grow well and yield good products as compared to plants originating from natural forests, so it is feasible to continue basing new plantations on existing ones, and (2) that introduction of new material from some natural forests may increase the possibilities for further improvement in yield and wood properties.

Resumen.Durante el período de 1969–1974, un grupo de expertos en Recursos Genéticos Forestales de la FAO, organizó esfuerzos al nivel internacional para explorar los recursos genéticos de la Gmelina arborea, Linn., Roxb. (gmelina). Como un primer paso hacia este esfuerzo, en 1975 la FAO de Dinamarca Forest Tree Seed Centre (luego Danida Forest Seed Centre) inició, en conjunto con organizaciones del sector público y privado de más de 20 países, un experimento internacional de procedencias. El experimento incluyó 36 procedencias de poblaciones naturales en India y Tailandia junto con 24‘razas locales’ de 20 países. Las procedencias se incluyeron en 60 ensayos de procedencia, los cuales fueron establecidos a mediados de los 70, por más de 20 países anfitriones. En este artículo se presenta un resumen del desempeño de las procedencias de las diferentes regiones de la India, Tailandia, y de las plantaciones exóticas en varios países. Los resultados muestran (1) que las plantas originarias de plantaciones exóticas crecen bien y ofrecen buenos productos, comparadas con las plantas originarias de bosques naturales, por lo cual se puede concluir que es posible continuar desarrollando nuevas plantaciones de plantaciones existentes, y (2) que la introducción de material nuevo procedente de algunos bosques naturales, puede aumentar las posibilidades para mejorar aún más el rendimiento y las propiedades de la madera.
