Resumen:
The additive (Ð2A) and the error (Ð2e) variance components, and the heritability (h2 = Ð2A / (Ð2A +Ð2e)) of the diameter at breast height (DAP) from crossbred pines (Pinus elliottii. var. elliotti. L Pinus caribaea var. hondurensis), were estimated using a bayesian approach by Gibbs sampling using a mixed individual tree model. The marginal posterior distributions of Ð2A, Ð2e and h2 were regular and symmetric, whereas similar values were found for the means, medians and modes. The posterior mean (and the standard deviation) for h2 was 0.106 (0.020).
