Age trends in genetic parameters of wood density components in 46 half-sibling ...
Gaspar, Maria João; Louzada, José Luís; Silva, Maria Emilia; Aguiar, Alexandre; Almeida, Maria HelenaThis study contributes to the Pinus pinaster Ait. breeding programme, which is reaching the third generation by adding information on wood quality of 46 open-pollinated families from a progeny trial located in Leiria, Portugal, that originated from seed collected in a clonal seed orchard. A total of 552 seventeen-year-old trees were sampled at 2 m height. Trends were studied from the pith outward in variance co...
Genetic correlations between wood quality traits of Pinus pinaster Ait.
Gaspar, Maria João; Louzada, José Luís; Aguiar, Alexandre; Almeida, Maria Helena• It is essential to understand how characteristics are related to each other in breeding programmes to select wood properties, in order to avoid that, in selecting for one trait, we are negatively affecting another. Moreover, measuring wood properties is time consuming and expensive. • This study assesses genetic and phenotypic correlations between wood density components and spiral grain of 46 half-sib famili...
