Evaluation of the breeding potential in height growth for Acacia mangium Willd.
In 2009-10, in Ayapel, Planeta Rica and Tierralta, Cordoba department (Colombia) the growth performance in overall height of 90 open-pollinated farnilies of Acacia mangium was evaluated. In these municipalities the climate is classified, according to Holdridge, like tropical dry forest (TDF), except Tierralta that it is tropical moist forest (TMF). During the first year of growth, plants in each farnily were evaluated in progeny tests using a randomized experimental complete block design, with six blocks in each of the three locations. The experimental unit consisted of six open-pollinated plants per farnily, randomly distributed in three spatially separated pairs within each block. The prediction of genetic pararneters individual and of farnilies was conducted by the method BLUP (best linear unbiased prediction) and the variance components by REML (restricted maximum likelihood) procedure using the software SELEGEN. Heritability estimates ranged from
