Quantitative trait loci mapping of forest productivity traits was performed using an open pollinated half-sib family of Eucalyptus grandis. For volume growth, a sequential QTI, mapping approach was applied using bulk segregant analysis, selective genotyping and consegregation analysis. Despite the low heritability of this trait and the heterogeneous genetic back ground employed for mapping, BSA detected one potative QTL for volume growth were found to control 13.7% of the phenotypic variation, corresponding to an estimated 43,7% of the genetic variation For wood specific gravity five QTL were identified controlling 24,7% of the phenotypic variation corresponding to 49% of the genetic variation. |
