Developing breeding objectives for radiata pine structural wood production. I. Bioeconomic model and economic weights

Abstract: Economic breeding objectives were developed for production of radiata pine (Pinus radiata D. Don) structural timber in Australia. Production systems of eight companies, including plantation growers, sawmills, and integrated-system companies, were examined. A bioeconomic model linking the breeding-objective traits mean annual increment (MAI), stem sweep, average branch size, and modulus of elasticity (MoE) with production-system components was constructed using data obtained from industry and published sources.… Show more

“…properties for structural wood products (Zobel and Van Buijtenen 1989;Zobel and Jett 1995;Hannrup et al 2004) and are thus the most important traits for tree breeding selection targeting the improvement of structure products (Ivković et al 2006). Traditional measurements of these traits are, however, either expensive or destructive, particularly for MFA and MOE.…”

“…Con ello, el volumen toma mayor ponderación y como resultado el valor del diámetro menor resulta mayor al de la regresión parcial y el del módulo de elasticidad dinámico menor. En Australia, Ivković et al (2006) valoraron el MoE d en 865 US$ ha -1 con un modelo bioeconómico en un sistema verticalmente integrado. En el mismo estudio, el valor MoE d a nivel de aserradero fue 9,3 US$ GPa -1 .…”

“…Contrariamente, Xu y Walker (2004) indican que este atributo tiene un efecto negativo en la producción de madera estructural. De igual modo, Ivković et al (2006) reportan un valor de -1,75 US$ cm -1 para IRa en una muestra de 95 mil trozas, hecho que les permitió acceder a una alta variabilidad del atributo. Así, las diferencias metodológicas entre enfoques y las características de la muestra serían los factores que determinan que el valor de IRa sea negativo o cero.…”
